General Instructions, Notices, and Warnings 

WARNING 

Installation, disassembly, repair and maintenance must be performed only by 

qualified personnel. 

All gas must be isolated from the product to be repaired. Evacuate or isolate as 

necessary and as indicated in any instructions. 

Installation, usage and maintenance of RegO ® Products must be in compliance with 

all Enigneered Comtrols International, Inc. instructions as well as requirements and 

provisions of NFPA # 54, NFPA # 58, DOT, ANSI, all applicable federal, state, 

provincial and local standards, codes, regulations, and laws. 

Inspection and maintenance of RegO ® Products on a periodic basis is essential. 

When available, be sure all instructions are read and understood before installation, 

operation and maintenance. These instructions must be passed along to the end user of 

the product. 

CAUTION 

Contact or inhalation of liquid propane, ammonia and their vapors can cause serious 

injury or death! NH3 and LP-Gas must be released outdoors in air currents that will 

ensure dispersion to prevent exposure to people and livestock. LP-Gas must be kept 

far enough from any open flame or other source of ignition to prevent fire or explosion! 

LP-Gas is heavier than air and may not disperse or evaporate rapidly if released 

in still air. 

NOTICE 

Repairs must be performed in a clean area. Hands, clothing, tools and work area must 

be completely free of oil, grease and foreign matter to prevent contamination of 

component parts and valves.

Determing The Age of Products 

All ECII ® products are mechanical devices that will eventually 

become inoperative due to wear, contaminants, corrosion 

and aging of components made of material such as metal 

and rubber. 

The environment and conditions of use will determine the 

safe service life of these products. Periodic inspection and 

maintenance are essential. 

Because ECII ® products have a long and proven record of quality 

and service, LP-Gas dealers may forget the hazards that can 

occur because products are used beyond their safe service life. 

The life of a product is determined by the environment in which it 

“lives.” The LP-Gas dealer knows better than anyone what this 

environment is. 

Since 1960, most RegO ® / ECII ® products are identified with an 

alphabetical code indicating the month and the year they were 

manufactured. 

Check the product for this code to determine age. If valves or regulators 

are repainted, take care to keep the date code clear for 

later identification and inspection. 

1960 to 1985 — Two-Letter Date Code 

First letter in date code is the month 

A — January 

G — July 

B — February H — August 

C — March I — September 

D — April J — October 

E — May 

K — November 

F — June L — December 

Relief valves used on ASME tanks carry a numerical code indicating 

month and year such as 1-75 means January, 1975. 

Second letter in date code is the year 

R — 1960 A — 1969 J — 1978

W— 1965 F — 1974 O — 1983 

X — 1966 G — 1975 P — 1984 

Y — 1967 H — 1976 Q — 1985 

Z — 1968 I — 1977 

EXAMPLE: DL = April of 1980 

From 1985 to 1990 — Digit Date Code 

First digit in date code is the month 

1 — January 7 — July

out of such defect. 

This warranty does not extend to any product or part that is not installed and 

used in accordance with Engineered Controls International, Inc.’s printed 

instructions, all applicable state and local regulations, and all applicable

WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 

PURPOSE, with respect to its products and parts, whether used alone or in 

combination with others. Engineered Controls International, Inc. disclaims all 

warranties not stated herein. 

LIMITATION OF LIABILITY 

Engineered Controls International, Inc.’s total liability for any and all losses and damages 

arising out of any cause whatsoever shall in no event exceed the purchase

cause be based on theories of contract, negligence, strict liability, tort or otherwise. 

Engineered Controls International, Inc. shall not be liable for incidental, consequential 

or punitive damages or other losses. Engineered Controls International, Inc. shall 

not be liable for, and buyer assumes liability for, all personal injury and property damage

If Engineered Controls International, Inc. furnishes technical advice to buyer, whether 

or not at buyer’s request, with respect to application, further manufacture or other 

use of the products and parts, Engineered Controls International, Inc. shall not be 

liable for such technical advice and buyer assumes all risks of such advice and the 

results thereof. 

NOTE: Some states do not allow the exclusion or limitation of incidental or consequential 

damages, so the above limitation or exclusion may not apply to you. The 

warranty gives you specific legal rights, and you may have other rights that vary from 

State to State. The portions of this limited warranty and limitation of liability shall be 

considered severable and all portions which are not disallowed by applicable law

personnel only, using accepted governmental and industrial safety procedures. 

NOTICE TO USERS OF PRODUCTS 

The Limited Warranty stated above is a factory warranty to the first purchasers of

must within thirty (30) days after the user’s discovery of what user believes is a 

defect, notify in writing the distributor from whom he purchased the product/parts. 

The distributor may or may not at the distributor’s option choose to submit the product/parts 

to Engineered Controls International, Inc., pursuant to its Limited Warranty. 

Failure by buyer to give such written notice within thirty (30) days shall be deemed 

an absolute and unconditional waiver of buyer’s claim for such defects. Acceptance 

of any alleged defective product/parts by Engineered Controls International, Inc.’s 

distributor for replacement or repairs under the terms of Engineered Controls 

International, Inc.’s Limited warranty in no way obligates Engineered Controls

a high quality leak detection solution. 

NOTE: It is recommended that pull-away valves be maintained and 

safely tested periodically to confirm that they will separate properly 

in the event of a pull-away. Lubrication on a monthly basis is 

essential to the pull-away’s operation. Dry nitrogen or other inert 

gas is suggested as a source of pressure for pull-away tests. 

Underwriters Laboratories requires the male end of the coupling be 

lubricated at least every six months. 

If the pull-away valve is going to be stored for a period of time, such 

as in seasonal applications, it is recommended that it be sprayed 

with a good grade of rust-preventative machine oil or covered to 

protect from moisture. A test should be conducted to confirm 

proper performance, including a simulated pull-away, prior to 

putting the pull-away valve back in service.

WARNING 




























Printed in U.S.A. 05-0699-0187 




Regulators must be removed from the system before starting 

repairs. Regulators must never be repaired while installed in the 

system. 

All repaired regulators must be properly bench tested for performance 

and leakage before being placed back in operation. Do not 

repair any regulator if proper bench testing equipment is not 

available. All parts included in the repair kit must be used, and the 

instructions followed. Failure to use all parts, follow all instructions 

and bench test the repaired regulator will probably result in faulty 

performance. 







Regulators should have a casual inspection for corrosion by 

examining the surface and looking into the bonnet after the bonnet 

cap has been removed. This sometimes will alert the inspector to 

corrosive conditions. Certainly, if there is any evidence or suspicion 

of corrosion the system should be shut down. The adjusting 

screw and spring should be removed and the bonnet should be 

examined with a strong flashlight. 

If any corrosion is evident, replace the regulator. 


















A. Disassembly: 

1. Clamp mounting legs of regulator body securely in vise. 

2. Use a wrench on the hex portion of inlet nipple. Unscrew inlet nipple 

by turning clockwise (left-hand thread) from body. 

3. Discard inlet nipple and inlet nipple seal. 

4. Using a 1 /2" hex socket wrench, unscrew seat disc assembly turning 

counterclockwise from plunger inside regulator body. Discard seat 

disc assembly. Be careful not to damage threads. Leave regulator 

in vise.

NOTE: When servicing obsolete 3100 and 7100 Series cylinder 

valves, a conversion to the o-ring style trim is preferred to straight 

repair. The o-ring style assembly provides construction that is 

more resistant to over-torquing on closure or opening to the backseated 

position. Installation in the field is easier, due to metal-tometal 

makeup between the body and bonnet and the elimination of 

retaining compound as a thread sealant. Order Engineered Controls 

International, Inc. repair kit 3100-81K for conversion to the o- 

ring style.

2. Using a screwdriver, remove the handwheel screw and washer by 

turning counterclockwise--thus allowing removal of the handwheel. 

Save these parts for reassembly. 

3. Place the valve body securely in a vise or hold the body with a 

wrench if still in the cylinder. Remove the bonnet, turning counterclockwise 

(right hand thread). A substantial wrench must be used 

as the bonnet was originally installed using retaining compound. 

Attached to the bonnet will be the valve stem and diaphragm 

assembly. 

4a. If using repair kit 3100-80A, discard the entire diaphrgam, bonnet 

and stem assembly. Proceed to the reassembly instructions. 

4b. If using repair kit 3100-80B, follow all of the remaining disassembly 

and reassembly instructions. 

5. Detach the diaphragm assembly from the bonnet and valve stem by 

turning the square of the valve stem in a clockwise (right hand) 

direction to remove the stem from the bonnet The diaphragm 

assembly may be detached by sliding the diaphragm stem head out 

of the slotted opening of the valve stem. Remove the backseat 

washer from the stem. Discard the diaphragm assembly, and 

backseat washer, and save the bonnet and stem assembly. 

B. Reassembly 

1. Brush the threads of the bonnet with a wire brush to make the 

thread surfaces as clean as possible by removing old retaining 

compound and other foreign materials present which may prevent 

a tight seal. The female threads in the valve body from which the 

bonnet was removed cannot be cleaned satisfactorily with a wire 

brush. To remove the old compound, use a 1 1 /16"-18 NEF-2 thread 

tap (available from local sources). Care must be used in applying 

the tap so that it starts squarely in the body threads. If oil or grease 

is present on the body or bonnet threads, it should be removed with 

a suitable solvent. 

CAUTION: Do not scratch or mar seat area in valve body. 

2a. If using repair kit 3100-80A, proceed to step 3. 

2b. If using repair kit 3100-80B, place new backseat washer over 

stem and insert into bonnet. Slide the stem head of the new 

diaphragm assembly into the slotted opening of the valve stem of 

the bonnet and stem assembly. Turn the square of the valve stem 

counterclockwise until the diaphragm is almost touching the 

bottom of the bonnet.

3. At this point you will have either a completely new diaphragm, 

bonnet and stem assembly or a bonnet and stem assembly with a 

new backseat washer and diaphragm assembly. In either case, be 

sure the diaphragm is positioned so that it almost touches the 

bottom of the bonnet. This is accomplished by turning the valve 

stem. 

4. Turn the square of the valve stem counterclockwise so that the 

diaphragm touches the bottom of the bonnet just enough to keep 

it in place. Add 1 /4 to 1 /2 counterclockwise turns to cup the 

diaphragm slightly. This is important as it positions the diaphragm 

properly so that when the valve is completelyassembled, the bonnet 

and body will grip the diaphragm properly and supply sufficient 

slack to permit the valve to open and close without undue strain on 

the diaphragm. 

5. Carefully apply one 1 /8" strip of loctite around the bonnet threads 

approximately two threads up from the diaphragm end. Never 

apply loctite directly to the female body thread, because the bonnet 

will push the loctite ahead of it and come in contact with the 

diaphragm and result in damage to the diaphragm. 

NOTE: Do not allow loctite to contact the diaphragm or seat disc. 

6. Install the diaphragm, bonnet and stem assembly into the valve 

body turning clockwise and tighten to 250 inch-lbs. torque. This 

torque is extremely important and therefore a torque wrench must 

be used. Allow loctite to dry. 

7. It is advisable to spot check some of the bonnet body joints after the 

loctite has hardened for a period of at least 24 hours. Using a torque 

wrench, the torque necessary to break this seal must be at least 300 

inch-lbs. If the seal can be broken at lower torque the parts were 

not properly cleaned or the loctite was not properly applied. This 

torque must be at least 300 inch-lbs. to assure that the bonnet does 

not loosen and come out in service, which would result in a 

hazardous condition that could result in fire and personal injury. 

8. Reassemble handwheel to valve stem and secure with screw and 

washer. Tighten firmly with a screwdriver. Check valve for proper 

operation. 

9. Turn handwheel fully clockwise to close valve. If valve was removed 

from the cylinder, reinstall the valve. 

10. Pressurize cylinder. Check all seal points for leaks by applying a 

high quality leak detection solution.

LP-Gas must be kept far enough from any open flame 

or other source of ignition to prevent fire or explosion! LP-Gas 

is heavier than air and may not disperse or evaporate rapidly 

if released in still air. 

Conversion To O-Ring Construction 

When servicing the obsolete 3100 and 7100 cylinder valves, a 

conversion to O-ring style trim is preferred to a straight repair. 

The new assembly provides construction that is more resistant 

to over-torquing on closure or opening to the backseated 

position. Installation in the field is easier, due to metal-to-metal 

makeup between the body and bonnet and the elimination of 

litharge cement as a thread sealant. 

The 3100-81K conversion assembly, illustrated, utilizes a new 

bonnet and replaces the diaphragm type trim with the O-ring 

type. Only the handwheel, screw and washer from the old 

assembly are retained. 




THIS SHEET, BEFORE BEGINNING ANY DISASSEMBLY OR 

REPAIR. 

NOTE: Repairs must be performed in a clean area. Hands, 

clothing, tools and work area must be completely free of oil, 

grease and foreign matter to prevent contamination of component 

parts and valves. 

Maintenance may be performed with the valve installed or 

removed from the cylinder. In either case, all gas must be 

evacuated from the cylinder before starting repairs. 



DISASSEMBLY OR REPAIR. Turn the handwheel 

counterclockwise as far as it will go to release any gas 

remaining in the container. CAUTION: Do not apply force 

after valve is fully open. 

2. Remove and discard screw and handwheel. 

3. Unscrew bonnet counterclockwise. A substantial wrench 

must be used because the bonnet was originally installed 

with litharge cement. 

NOTE: Hold the body with a second wrench when removing 

bonnet if valve is repaired while on cylinder. If valve is out of 

cylinder, clamp the body in a vise. 

4. Remove and discard bonnet, valve stem, and diaphragm 

assembly.

3100 and 7100 Cylinder Valves 

5. Remove any noticeable build-up of old litharge cement or any 

foreign materials in valve body threads with a 1 1 /16"-18 NEF 

- 2 thread tap, obtained from a local source. Apply tap 

carefully so that it starts squarely in the body threads. If oil or 

grease is present on threads, it should be removed with a 

suitable solvent. 

6. Inspect remainder of valve body and clean if necessary. Be 

sure interior is free of dirt, residue, and foreign particles. Be 

sure assembly is in good repair. 


B. Reassembly 

1. Completely coat the gasket with 5555GP grease (must be 

ordered separately. One can is sufficient for 100 

conversions). 

2. Position gasket into valve body. 

3. Thread new bonnet, stem and o-ring assembly into the valve 

body clockwise and tighten to 600-900 in/lbs. torque using 

a suitable wrench. 

4. Assemble screw and handwheel to valve stem. Hold 

handwheel and tighten firmly. 

5. If valve was removed for repairs, re-install on cylinder. 

6. Check valve for proper operation by cycling 1 /4 to 1 /2 turn in 

a clockwise and counterclockwise direction. Close valve, 

pressurize system, and check all seal points for leaks by 

applying a high quality leak detection solution.

Pneumatic Actuator Installation: 

NOTE: Lubricant compound 11550-215, or the equivalent, 

should be applied in a light coating when specified. Torque 

tolerance is +/- 10 lbs. Refer to Diagram 2 during assembly of 

the pneumatic actuator. 

a. Remove the clevis and clevis locknut from the air chamber shaft. 

Remove cotter pin and pivot pin from the clevis. 

b. Assemble the air chamber to the bracket using the air chamber 

nuts and lock washers. Center the air chamber shaft in the 

clearance hole of the bracket. Tighten air chamber nuts to 375 

in/lbs. 

c. Reassemble the clevis locknut and clevis to the air chamber 

shaft. Adjust the clevis so that the center of the pivot pin hole is 

2 3 /4" from the bracket with the pivot pin holes in the horizontal 

plane. Lock the clevis in place with the clevis locknut using 200 

in/lbs torque. 

d. Mount the above bracket assembly to the valve face with the 

bracket screws and lock washers. Be sure that the top of the 

bracket is even with the upper edge of the valve face and 

centered around the hex of the packing gland. Torque the 

bracket screws to 60 in/lbs. 

e. Assemble the crank arm onto the valve stem so that the crank 

arm leg clears the clevis legs. Rotate the crank arm so the leg 

positions itself between the legs of the clevis. Align cotter pin 

holes and secure with the cotter pin. Spread and bend the ends 

of the pin back onto the hub. 

f. Assemble the two pivot pin washers onto the pivot pin. Lubricate 

the pivot pin shaft and assemble through the holes of the clevis 

legs and crank arm leg. The air chamber shaft can be displaced 

manually along with movement of the crank arm to effect 

alignment. Once the pivot pin is engaged, check to see that the 

crank arm leg is at approximately 35 ° to the vertical. If bench 

assembled, the cam should be horizontal, or slightly below 

horizontal, and the clearance between the cam and the end of 

the poppet should measure 3 /16" + /- 1 /64". 

Should an adjustment be necessary, follow these procedures: 

i) Remove the pivot pin and pivot pin washers. 

ii) Rotate the crank arm counterclockwise until the leg clears the 

clevis. 

iii)Loosen the clevis locknut and adjust the clevis appropriately, 

in or out. A half a turn of the clevis changes the angle 

approximately 3 /4 degree, or the cam/poppet clearance by 

.010". 

iv)Reassemble the pivot pin and the pivot pin washers. Check 

again for proper angle/clearance. Once correct, lock the 

clevis in place with the clevis locknut. 

v) Assemble the cotter pin into the pivot pin hole. Spread and 

turn back the cotter pin legs around the pivot pin shaft. 


Connect a 50 to 60 psig air line through a pressure regulated valve to the 

actuator. 

Bench Testing 

Slowly and alternately apply 0 to 35 psig air pressure to the actuator two 

or three times while checking for binding and any interference. Make any 

necessary adjustments so the actuator opens freely . Be sure the 

actuator shaft bottoms out on the actuator housing at full stroke and not 

within the valve. 

Installed Testing 

Same as the bench test, except a higher air pressure may be necessary 

if tank pressure is present.

2. Depress upper check to assure lower check is functioning properly. 

(Part number 3119A Unloading Adapter may be used to depress 

upper check.) If the lower check does not restrict the flow of gas 

from the valve, the upper body and check must not be removed 

because an uncontrolled, hazardous amount of gas will discharge 

from the valve. If this is the case, the container must be 

emptied and a new filler valve installed. 

If the valve is to remain on the cylinder, hold the lower body with a 

second wrench to keep it from being unscrewed while removing the 

upper body.

NOTE: Before repairing valve, thoroughly examine valve for excessive 

wear and the operating lever for proper function. Any components 

that are not in good condition and fully operational should be 

replaced during repairs. 

Repairs must be performed in a clean area. Hands, clothing, tools 

and work area must be completely free of oil, grease and foreign 


Clean the valve body and all parts before reassembly. 

Disassembly 

1. Remove the two (2) acorn nuts which attach the cover to the valve 

body. Set aside for reassembly. 

2. Remove the cover and save for reassembly. If cables are attached 

for remote closure, let the cover hang loose. The cover may be 

used as a means of retaining parts removed that will be used 

during reassembly. 

3. Using a screwdriver, pry the retainer off the stem which holds the 

latching mechanism. Remove and save the retainer, latching 

mechanism and spring for reassembly. 

4. Using a pair of pliers, carefully disengage the return spring. 

CAUTION: Once the return spring is disengaged it will spring 

forward sharply. 

5. Using an allen wrench, loosen (but do not remove) the set screw. 

Remove the tripper and return spring from the shaft. Retain the 

parts for reassembly. 

6. Remove and discard nylon gasket. 

7. Remove and retain nut, washer and handle. 

8. Remove the eight (8) cap screws and washers. Using a small blade 

screwdriver, place it between the body and plate and pry apart 

slowly to remove plate. Save all parts for reassembly.

9. Remove the plate gasket and discard. 

10. To remove the flapper assembly, which incorporates the seat disc, 

the shaft must be twisted slightly while holding the flapper assembly 

in place. By using a pulling force on the shaft and twisting slowly, 

the squares will align in both pieces allowing the shaft to be pulled 

through and removed, In addition, the metal washer on the end of 

the shaft should be removed. Retain the shaft and metal washer for 

reassembly. Discard the flapper assembly. 

NOTE: The remaining disassembly steps involve removal of each seal 

housing. When required, complete each step for each of the two (2) seal 

housings. 

11. Using a 1 3 /8" wrench, with a handle of sufficient length to develop 

a minimum of 1000 in/lbs torque, loosen each seal housing counterclockwise. 

Remove and save. If the valve is in the system, place 

the plate onto the body and hold in place using the cap screws 

during seal housing removal. 

CAUTION: Be careful not to scratch or mar the finish on the shaft. 

12. Remove and discard the four (4) pressure seal rings and two (2) shaft 

O-rings from the seal housings. Retain seal housings. 

13. Remove and retain the shaft. 

14. Remove and retain spring. Remove and discard two (2) seal 

housing gaskets, two (2) seal housing washers and two (2) jam rings 

from body and plate. 

NOTE: Inspect shaft surface for scratching or scoring. Inspect seal 

housing threads for wear or damage. Replace if necessary. 

Reassembly 

NOTE: Be sure all parts are clean. 

1. Install two (2) new seal housing gaskets, spring, two (2) new seal 

housing washers and two (2) new jam rings onto body and plate. 

2. Install two (2) new shaft O-rings into groove of each seal housing. 

3. Spray a thin film of #5555MK grease onto the four (4) new pressure 

seal rings and carefully insert them one at a time into the full depth 

of each seal housing (2 per housing). 

4. Apply #5555LT loctite across the threads in three places equally 

spaced around each seal housing. 

CAUTION: Do not allow loctite to contact rubber components. Use 

sparingly. 

5. Thread each seal housing into position clockwise. Tighten to 800 

in/lb torque with a 1 3 /8" wrench. 

6. Place the metal washer and new flapper assembly onto the shaft. 

Slowly insert the shaft through the bearing in the body and seal area 

until the flapper is directly in line with the valve seat in the body. 

Operate manually to make sure the valve is not jammed. 

7. Apply a thin film of #5555GS-8 grease to the new plate gasket. With 

the new plate gasket in position, assemble the plate to the body and 

check for proper shaft rotation. 

NOTE: There should be a slight drag on the shaft. 

8. Secure the plate to the body with the eight (8) cap screws and 

washers. Apply a light torque to screws in four corners using a 

clockwise rotation, top to bottom and left to right. At the same time, 

move the shaft to make sure that no excessive binding occurs. 

Tighten down these four screws and be sure shaft moves freely. 

Tighten the other four screws. 

9. Assemble the nylon gasket and return spring onto shaft on plate 

side of assembly. On the other side, assemble the handle to the 

shaft with the nut and washer and tighten. Be sure that when the 

flapper assembly seat disc is closed that the handle is in the down 

position. 

10. Assemble the latching mechanism onto shaft and insert wire from 

return spring into the latch hole. Take the other end of the return 

spring and pull back to where hex stem is inserted and place loop 

of spring over hex, making sure the loop of the return spring rests 

in the undercut of the stem. If the loop is too large, bend slightly into 

place using pliers. At this time, there should be tension on the return 

spring and the valve should close quickly. If this does not happen, 

the valve must be reworked. Once functioning properly, tighten the 

set screw into the tripper being careful not to overtighten. 

11. Assemble spring and latching mechanism onto stem. Be sure that 

Tripper (7605-9) Set Screw (7605-39) 

Detail of Flapper Assembly 

once in place, one end of the spring is connected to the latch 

mechanism and the other end rests on top of the return spring. At 

this point, there should be tension on the latching mechanism which 

should readily bring it back and forth. If this does not occur, the 

spring is improperly assembled and must be corrected. Securely 

assemble the retainer onto the stem to retain the latching mechanism. 

Cycle the valve. As each cycle occurs, the tripper should 

catch into the open area of the latching mechanism on each opening 

If this does not occur, the latching mechanism must be removed 

and corrected. 

12. Pressurize the system and check all seal points for leaks by applying 


13. Attach the cover and secure with the two (2) acorn nuts. 

14. Check the valve for proper operation by immediately performing the 

shutdown test as described in the Inspection and Maintenance 

Program, that is recommended every six (6) months. 

Ispection and Maintenance Program 

WARNING: The Emergency Shut-Off Valves and their control 

systems are mechanical devices and must be inspected, maintained 

and operated at regular intervals if they are to ensure 

protection of your plant. Make all adjustments and repairs to the 

ESV or control system immediately upon discovery. 

Follow these routine check lists. Since each ESV system is unique, the 

check lists are not all-inclusive. Therefore, add your individual installation 

requirements as needed. 

Daily: 

With the ESV open, trip the latch and make sure the valve handle moves 

to the closed position (perpendicular to the piping). 

NOTE: Without liquid or vapor flow, the valve handle may rotate slowly 

when released. This occurs particularly when line pressures are high or 

when the valve handle has not been moved for a long time.

Monthly: 

1. Check the transfer hose release cable. Be certain all clamps are 

secured properly and that the cable is adjusted to trip the latch when 

the hose is stretched. 

2. Check all remote release cables. Be certain that all cables are 

properly installed to ensure that the latch releases when the cable 

is pulled from all remote locations. 

3. Check that all instruction signs are visible and legible. 

4. Inspect the entire system for damage, wear, or corrosion, and repair 

or replace components as needed. 

5. Check the pneumatic shutdown system, if applicable, to ensure that 

the charging valve and all operating valves are in good working 

order, that all tubing is free of kinks or damage and that the control 

pressure is between 20 and 50 PSIG. 

Every 6 months: 

Perform the appropriate shutdown test. 

1. Delivery truck loading: Trip the latch on the ESV in the liquid line to make 

sure the ESV closes rapidly with the pump or compressor running. 

CAUTION: Immediately after tripping the latch, shut off the pump 

or compressor to prevent excessive differential pressures and 

possible damage to the pumping system. 

2. Transport unloading: Trip the latch on the ESV in the vapor line when 

the pressure in the transport is at least 25 PSIG less than that in the 

storage tank to make sure the ESV closes rapidly. (One way of 

creating the pressure difference is to shut off the vapor equalizing 

line while unloading the transport.)

distribution of lubrication. 

NOTE • If the handle is too tight and will not move, loosen the 

gland until handle moves with a fair amount of ease. 

See Step 5. 

• If the handle moves too freely, it is an indication that 

the gland is too loose. The gland must be tightened 

or it will leak. 

Re-Installing the Manifold Assembly 

If the manifold was removed from the container, replace with the 

following steps: 

1. Apply a suitable non-hardening pipe compound to the male 

threads of the lower manifold body. 

NOTE: Do not apply compound to the female threads in the 

container coupling. 

2. Thread the manifold into the container port hand tight. 

3. Using an appropriate wrench applied directly to the lower 

body of the manifold, tighten the manifold into the container 

with a sufficient torque to provide a leak tight seal. 

Relief Valve Replacement 

1. Apply a small amount of a suitable non-hardening pipe 

compound to the male threads of the relief valves. 

NOTE: Do not apply compound to the female threads in the 

manifold port. 

2. Thread relief valves into manifold assembly hand tight. 

3. Using an appropriate wrench on the hex section of the relief 

valves only, screw valves in approximately 1 1 /2 additional 

turns. Tighten valves with a sufficient torque to provide a 

leak-tight seal. 

Placing Relief Valve Manifold Back into Service 

Turn the knob of each bleeder valve counterclockwise until it is 

fully back-seated. See Figure 2. During normal operation, the 

bleeder valve should be left in this position. 

During normal operation, with the relief valves properly in place, 

the positioning handle should be kept at the center stop 

position. In this position, both relief valves are open to the 

container vapor space, providing extra relief capacity by 

permitting both valves to function simultaneously if necessary. 

Check the connection of the replaced relief valves and manifold 

using a high quality leak detection solution. If bubbles appear, 

there is a leak. The connection must be leak tight.

2. Screw the seat ring assembly into the compression ring until 

it is flush at top. 

3. Apply a light grease to the seat ring body threads. 

4. With the shut-off disc under the relief valve port, insert seat 

ring and compression ring assembly into the port and screw 

in by hand as far as possible. 

5. Use a wrench to adjust the depth of the seat ring. The seat 

ring should be positioned so that when the shut-off disc is 

moved with the handwheel, the shut-off disc remains in 

contact with the seat ring for approximately 1 /8" of travel. 

6. Turn the handwheel and approach the relief valve port from 

both sides with the shut-off disc. Make certain that the shutoff 

disc does not hit the seat ring from the side before 

seating. Make adjustments if necessary. 

7. While holding the seat ring assembly in place with a wrench, 

tighten the compression ring. 

Bleeder Valve Assembly Replacement 

Disassembly: 

1. Using a 1" hex wrench, turn the bleeder valve body counterclockwise. 

Remove and discard assembly. 

2. Visually inspect the port in the manifold body. Remove any 

debris or scale using care not to damage threads. 

Reassembly: 

1. Open new bleeder valve assembly to a fully back-seated 

position by turning bleeder valve knob counter-clockwise. 

See Figure 5.

2. Install relief valves into manifold assembly hand tight. 

3. Using a wrench on the hex section of the relief valves only, 

screw valves in approximately 1 1 /2 turns. Tighten valves with 

a sufficient torque to provide a leak-tight seal. 

NOTE: Make sure one of three weep hole deflector openings 

in relief valve faces outward. 

If this is not the opening previously used, remove plug from 

outward tapped opening and install in vacant opening of relief 

valve using a pipe compound on male threads of plug. 

4. Apply pipe compound to the male threads of the weep hole 

deflector and install into outermost tapped opening of the 

relief valve. The deflector must be installed so that the large 

angle bore points up. 

NOTE: Be sure the remaining two openings are plugged. 

Placing Relief Valve Manifold Back into Service 

Turn the knob of each bleeder valve counterclockwise until it is 

fully back-seated. See Figure 5. During normal operation, the 

bleeder valve should be left in this position. 

During normal use, with all relief valves properly in place, it is 

recommended that the handwheel be turned so that the shut-off 

disc is positioned between any two adjacent relief valves. This is 

accomplished by positioning the handwheel so the arrow on the 

manifold body points between any two numbers on the 

handwheel. This will provide extra relief capacity so that all of the 

relief valves can function if necessary. 

After the container is pressurized, check the seal of the flange 

makeup by applying a high quality leak detection solution. If 

bubbles appear, tighten the bolts until the flange seals. If this 

does not work, the flanged surface needs to be checked. 

Check the connection of the replaced relief valves and manifold. 

If bubbles appear, there is a leak. The connection must be leak 

tight.

NOTE: All ECII ® products are mechanical devices that will eventually 

become inoperative due to wear, contaminants, corrosion and 

aging of components made of materials such as metal and rubber. 

As a general recommendation, regulators should be replaced in 15 

years or less. 

The environment and conditions of use will determine the safe 

service life of these products. Periodic inspection and maintenance 

are essential. 

Because ECII ® products have a long and proven record of quality 

and service, dealers may forget the hazards that can occur 

because a regulator is used beyond its safe service life. The life of 

a regulator is determined by the environment in which it “lives”. The 

dealer knows better than anyone what this environment is. 

There is a developing trend in state legislation and in proposed 

national legislation to make the owners of products responsible for 

replacing products before they reach the end of their safe useful 

life. Dealers should be aware of legislation which could affect them. 

Foreword 

The 1580M Series Regulators are designed to reduce pressure to 

between 3 and 125 PSIG. They are accurate and dependable over 

a wide range of operating conditions, and come in a variety of sizes, 

capacities and designs to suit your needs. Precision built with multimillion 

BTU capacity, the 1580M Series is perfect for big, tough jobs 

such as crop drying, asphalt batch mixing, road building (tar 

wagons), heat treating, high volume space heating and other large 

industrial and commercial loads. It is ideal as a first stage 

regulator. The AA1580M Series is ideal for use in anhydrous 

ammonia applications such as blue print machines and heat treating. 

A large nozzle and straight-through flow provide high capacity 

and resistance to freeze-ups. 

Installation 

Clean dirt and foreign material from all piping and fittings. Be sure 

the regulator’s inlet and outlet are correctly installed in-line according 

to the designed flow pattern and markings on the regulator 

body. Thread sealants used on piping must be compatible with the 

system’s service. Pressure gauges must also be suitable for this 

service. Pressure gauges must be UL listed if 1,000 PSIG or higher. 

Regulators must be positioned to protect vents from the elements 

of ice, snow drifts, rain, dirt, bugs, paint, or other foreign material. 

If used indoors, LP-Gas regulators must be in accordance with 

NFPA #58 and local codes. 

These regulators are suitable for use in both vapor and liquid 

service. Caution must be exercised with liquid service where the 

application involves trapping liquid between the regulator and a 

shut-off valve, either upstream or downstream of the regulator. Any 

hose or piping that may hold trapped liquid should be protected by 

installing a Hydrostatic Relief Valve (such as the ECII ® 3127 Series 

for LP-Gas Service and SS8021 Series for NH3 Service) or their 

equivalent.

Operation 

The 3 /4" and 1" Pull-away valves are designed to provide pull-away 

protection for LP-Gas and NH3 transfer operations. These include 

transport and delivery truck loading and unloading, engine fuel container 

filling and miscellaneous cylinder filling operations. When fastened to 

the inlet end of the discharge hose, the valve is designed to prevent gas 

escape from both upstream and downstream lines in the event of a pullaway. 

An excessive tension load will cause the pull-away to separate 

and allow the two internal back pressure checks to close-assuming the 

pull-away has been properly maintained and installed as set forth in 

these instructions. Only a few cubic centimeters of product will escape 

at the instant of separation. 

NOTE: The A2141A6 and A2141A8 Series Pull-Away Valves should 

not be installed more than 6 feet above the ground. 

Installation 

1. Mount valve assembly with bracket or lanyard positioned upstream. 

See illustrations. Use a 1 /2" hex head machine bolt or a 5 /16" U-bolt 

with suitable washers and nuts, or a 1 /8" (7 x 19 strand) stainless steel 

flexible aircraft cable having a tensile strength of approximately 1000 

lbs with suitable cable clamps. Valve assembly must be able to 

swivel to assure a straight pull in the event of a pull-away. 

2. Use a short length of hose between the rigid piping and the inlet of 

the pull-away valve. Approximately 12 to 24 inches in hose length 

should provide sufficient flexibility, depending upon the installation. 

3. Attach the discharge hose to the downstream end of the pull-away 

valve assembly. 

4. After the installation is completed and before the system is charged 

with LP-Gas or NH3, a pull-away test should be conducted to assure 

proper operation of the pull-away valve. 

NOTE: It is recommended that a convenient means be provided to 

safely remove the pressure from the line upstream of the valve assembly, 

enabling reassembly of the pull-away valve after a pull-away. 

WARNING: Always wear protective eye wear and gloves when 

disconnecting or reconnecting the pull-away valve. 

Reconnection 

1. Before reconnection, safely insure that all internal pressure has 

been removed upstream and downstream of the pull-away valve 

assembly. 

2. Apply a light film of ECII ® #5555GP grease or a good grade of rust 

preventative machine oil to the male end of the coupling. 

3. To reconnect, simply push the male coupling section into the female 

coupling section until the retaining balls snap into the groove.

Foreword 

The 2434A Low Pressure Test Set is designed to check for pressure 

loss due to leaks or line restrictions and proper adjustment of delivery 

pressure at appliances and regulator lock-up. This set should be used 

downstream of the single stage or second stage regulator, and upstream 

of appliance regulators and controls. The unit must be calibrated 

frequently with an actual water manometer to insure accurate readings. 

Engineered Controls International, Inc. recommends that all of the three 

tests outlined in this manual be performed any time a new regulator is 

installed or replaced, or if gas service is shut-off and service resumed. 

Test I: Leak Testing the Installation 

Step 1. Inspect all connections and appliance valves to be sure connections 

are wrench-tight and that all appliance valves are 

closed, including pilot valves. 

Step 2. Connect low pressure test set to the low pressure piping 

system just upstream of the appliance regulators and controls. 

Step 3. Fully open LP-Gas container valve slowly to pressurize piping 

system. Once the system is pressurized and stabilized, close 

container valve tightly. 

Step 4. Observe indicated pressure on the low pressure test set gauge. 

This reading should be approximately equivalent to the set 

delivery pressure of the final stage regulator, normally 11" water 

column. Now, slowly open one burner valve, or pilot valve, on 

appliance to vent off just enough gas to reduce pressure on test 

gauge by 1" water column, to normally 10" water column, then 

close the burner or pilot valve. 

If pressure remains unchanged on the gauge for at least 10 minutes, the 

system can be assumed to be leak-tight. If a drop in pressure does 

occur, it indicates a leak in the system. 

If pressure drop occurs, check joints, connections and other possible 

points of leakage with an approved, high quality leak detection solution. 

NEVER USE A MATCH OR OPEN FLAME TO CHECK FOR LEAKS. 

Once a leak has been located and repaired, repeat 3 and 4. If there is 

an increase in pressure, it indicates that the LP-Gas container valve is 

not shut-off tightly. Shut-off valve tightly and repeat step 4. 

NOTE: Do not expose final stage piping to excessive heat or direct 

sunshine during the leak test. Pressure build-up in the line due to heat 

may compensate for pressure loss due to leaks. This will prevent the 

gauge readings from indicating system leaks. 

2434A Low Pressure Test 

Set Operation Manual 

Test II: Regulator Delivery Pressure 

Fully open the container valve, light the pilots and check the final stage 

regulator delivery pressure with approximately one-half the total BTU 

appliance load in-use. The low pressure test gauge reading should be 

approximately equivalent to the factory set delivery pressure of the final 

stage regulator, normally 11" water column at the appliance. Following 

this, turn on all appliances to utilize the entire BTU load. Check the 

pressure gauge to insure that adequate pressure is maintained at full 

load. If excessive pressure drop occurs, inspect the low pressure line 

for kinks, flats, or other restrictions. Also refer to pipe sizing charts in the 

“ECII Serviceman’s Manual” or “ECII Technical Guide #101” to insure 

correct pipe sizing. “ECII L-500 LP-Gas Catalog” will give you maximum 

capacity ratings for ECII regulators. 

Test III: Regulator Lock-up and Leakage 

After the leak testing and delivery pressure tests have proven satisfactory, 

the regulator lock-up and leakage test may be performed. The 

lock-up pressure of the final stage regulator should be slightly higher 

than, but not more than, 120% of the set delivery pressure. For example, 

on a delivery pressure setting of 11" water column, the maximum 

allowable lock-up pressure is 13.2" water column. 

To perform the lock-up and leakage test, follow these steps: 

1. With the container valve fully open, shut-off all appliance valves so 

there is no demand for gas. This includes shutting off all pilots. 

2. A slight rise in pressure will occur under these conditions-this rise 

should be no more than 120% of the delivery pressure. This is the 

lock-up pressure. 

NOTE: A quick rise in pressure above the allowable lock-up point could 

indicate undersize line piping, a worn seat disc or foreign material in 

the seating area. This condition must be corrected before putting 

the system in service. 

3. Continue the test for five minutes or more. If a creeping rise in 

pressure is noticed, the final stage regulator seat is not closing off 

properly. The regulator must be replaced or repaired, and the 

system retested, before putting the system is service. 

Recalibrating the Gauge 

The 2434A Low Pressure Test Set uses a spring loaded gauge that will 

need to be recalibrated on a frequent basis. This is done by comparing 

the gauge readings to those of an actual water manometer. 

To recalibrate the gauge, first remove it from the case. Next, remove the 

two screws in the back of the gauge case and remove the plastic gauge 

face cover by unscrewing it counterclockwise. The gauge mechanism 

can be carefully removed from the casing to provide easy access to the 

calibrating screw located behind the dial. Set the calibrating screw while 

comparing readings with the water manometer readings. Once calibrated, 

the gauge can be reassembled and set back into the case. 

NOTE: It is extremely important that recalibration be done on a frequent 

basis to assure accurate testing and adjustment of the regulator delivery 

and lock-up pressure.

Gas must be kept far enough from any open flame or other source 

of ignition to prevent fire or explosion! LP-Gas is heavier than 

air and will not disperse or evaporate rapidly if released in still 

air. 

1. 3119A and 3120 Unloading Adapters are designed to provide 

a simple, safe means of container evacuation provided these 

instructions are carefully followed. 

NOTE: On 3120 models, it is recommended that a 3 /4" shut-off valve 

be installed at opening “G” – between the unloading adapter and 

the hose. 

2. The adapter makes use of the crank and lever principle to force 

the filler valve to the open position when it is necessary to evacuate 

liquid from an LP-Gas container. 

3. These unloading adapters are usable with the 2418, 2550, 2555, 

2557, 1475, 2593, 2594, 8593, 8594 and 8475 MultiValves and 

the 3178, 3179, 7579 and 7579P quick filler valves. 

4. The filler check valves of the 3178, 2418, 2550 and current 2555 

and 2557 (see paragraph 9 (f) for earlier production of 2555 and 

2557) require only 1 /4" movement to open both upper and lower 

check valves. Such filler valves are identified by a single V-groove 

cut across the hex corners of the body. 

5. Valves 1475, 2593, 2594, 8593, 8594, 8475, 3179, 7579 and 7579P 

require a movement of approximately 1 /2" to fully open both upper 

and lower filler check valves. Since 1 /4" movement of the upper 

check valve is required before the lower check valve is opened, 

the lower check can still close even though upper check is held 

open by foreign matter. Such filler valves are identified by a double 

V-groove cut across the hex corners of the body. 

6. To allow for the interchangeable use of this unloading adapter with 

all of the filler valves referred to above, it is designed so that when 

the lever is rotated counter-clockwise from the “up” to the “down” 

position, the crank moves plunger “D” approximately 1 /2". Lever 

“A” should therefore, be rotated counter-clockwise (to the left) when 

used with 1475, 2593, 2594, 8593, 8594, 8475, 3179, 7579 and 

7579P valves. 

7. When the lever “A” is rotated clockwise (to the right) the crank moves 

plunger “D” approximately 1 /4". Clockwise rotation of lever “A” from 

the “up” to the “down” position should therefore be used when 

the adapter is fitted to the 3178, 2418, 2550, 2555 and 2557 valves. 

8. Before attempting to use the adapter it is of vital importance that 

you first make sure: 

a. That the filler valve on a container to be evacuated is equipped 

with a dip pipe extending to the bottom of the container. 

b. That if the container is equipped with a filler valve with a 

supplementary back pressure check valve - the design of the 

combination must be such that the lower valve (back pressure 

check) also opens when the upper valve (filler) is pushed open.

All of the combination and back pressure check valves listed 

above meet this requirement. 

c. Determine whether the lever ”A” is to be rotated clockwise or 

counter-clockwise. (See paragraphs 6 and 7 above.) 

d. That the unloading adapter assembly is not connected to the 

hose. 

9. After following instructions outlined in paragraph 8, the following 

operating instructions must be followed to operate the unloading 

adapter correctly and safely. 

a. Move lever “A” to “up” position (one-half turn from “down” 

position illustrated in drawing). If using 3120 model, remove 

cap assembly “F”. 

b. Place screw driver in slot “B” and turn counter-clockwise to 

move plunger “D” up as far as it will go without forcing. 

c. Place adapter on filler valve and tighten coupling nut “C”. 

d. Again place screw driver in slot “B” and turn clockwise slowly 

until plunger “D” barely contacts check in filler valve. This 

operation adjusts plunger to correct length. 

CAUTION: (1) If gas or liquid is discharged while plunger “D” 

is being adjusted, it indicates that plunger has 

been screwed in too far. If this occurs turn 

counter-clockwise until discharge ceases. 

(2) Do not move lever “A” as opening filler valve at 

this point will discharge liquid on your hands. 

e. Connect unloading hose to top of adapter or shut-off valve 

assembly. If using 3120 model, replace cap assembly “F”. 

f. After first determining direction of rotation to be used, turn lever 

“A” slowly toward its “down” position. 

WARNING: Do not force handle a full half-turn if it appears that 

filler valve is wide open before lever reaches a half-turn. In some 

makes of valves, the valve stem travel may be less than the plunger 

travel of the unloading adapter. In such cases, damage might 

be done to the filler valve if lever “A” were forced too far. In 

certain makes of valves, it is conceivable that the valve internal 

parts might be pushed into the container. However, if care is 

taken and lever “A” is turned just far enough to open the filler 

valve fully, no damage will occur. The original production of the 

2555 and 2557 Series MultiValves included filler valve assemblies 

having approximately 3 /16" check valve travel. Care must therefore 

be taken when using the unloading adapter with these valves. 

If it is found that the check valve travel is only 3 /16", the plunger 

“D” should be shortened 1 /16" by turning plunger “D” counterclockwise 

about two turns. A check valve travel of 1 /4" is provided 

in current production of the 2555 and 2557 Series MultiValves. 

g. Evacuate the container. 

h. Return lever “A” to the “up” position after evacuation is completed. 

Close shut-off valve on end of unloading hose. Open 

vent valve “E” on the unloading adapter to release any pressure 

remaining in adapter. Do not disconnect hose until vent valve 

“E” has ceased bleeding, thereby indicating that the filler valve 

is closed and has seated properly. 

i. When the vent valve "E" stops discharging liquid and gas, the 

unloading hose may be disconnected and the unloading adapter 

assembly removed from the filler valve. 

10. Care must be used in handling and storing Unloading Adapters 

so that they will not be damaged. They should be put in a protected 

place on the truck rather than stored unprotected in the tool box. 

11. Unloading operations should never be undertaken except by thoroughly 

trained and qualified operators.

1. The 3121 Unloading Adapter is designed to provide a simple, 

safe means of container evacuation provided these instructions 

are carefully followed. 

NOTE: On the 3121, it is recommended that a 3 /4" shut-off valve 

be installed at opening “G” – between the unloading adapter

the 3178, 3179, 7579 and 7579P quick filler valves. 

3. The filler check valves of the 3178, 2418, 2550 and current 

2555 and 2557 (see paragraph 6 (f) for earlier production of 2555

a. Place handwheel in full clockwise or close position The 

handwheel rises out of the valve body when placed in the 

closed position. 

b. Place adapter on valve and tighten coupling nut. 

c. Connect unloading hose to opening G or shut-off valve 

assembly. 

d. Turn handwheel in counter clockwise or open position.

Operation 

The 3200C Remote Cable Kit is designed for use with the 3200L 

Remote Operating Lever to operate internal valves from a remote 

location. The internal valve is opened by pulling back the remote 

operation lever and closed by returning the lever to its original 

position. A remote release is also provided to close the internal valve 

from a different remote location. Fuse links incorporated into cable 

system provide additional safety. 

Installation 

1. Install 3200L operating lever securely at desired location. 

2. Run cable through the 3 /8" center hole in front of the operating 

lever assembly. Attach cable to activating device by threading it 

through the provided clamping nut on the coupling and tightening. 

No fuse link is required on operating lever since fuse material 

is built into the coupling. 

3. Attach fuse link to operating lever of the internal valve with B- 

9403-17SS nut and A3217-36 bolt. 

NOTE: To attach fuse link on A3217, A7782, and A7783 series 

internal valves, it is necessary to drill a hole approximately 2 1 /4" from 

the original hole on the operating lever. 

WARNING: Drilling must be performed in an isolated area away 

from LP-Gas tanks or vessels, or exposure to LP-Gas and its 

vapors. The internal valve’s lever should be disassembled from 

valve at the lever crank connection--follow manufacturer’s 

installation and operation instructions included with the internal 

valve. 

WARNING: It is important to be sure that internal valve opens 

and closes properly with main operating lever before connecting 

cable. 

4. With both the 3200L lever assembly and the internal valve lever 

in the closed position, connect cable to the fuse link on valve with 

cable clamp.

A3209A050 1 1 /4" Internal Valve 

and A3209TL Latch Assembly 

Installation and Operation Manual



This valve must remain in the closed position except during 

product transfer. A line break downstream of the pump may fail to 

actuate the excess flow valve as the pump may limit flow. If a break 

occurs in the system, or the excess flow closes, immediately shut 

down the system. 

















Foreword 

The A3209050 1 1 /4" Internal Valve is designed primarily for use with 

propane, butane and anhydrous ammonia. It is intended for use as 

a main valve on small capacity pump systems. It may also be 

installed in the vapor return line and liquid withdrawal openings on 

trucks or in-line installations and in nurse tanks provided proper 

piping configuration is used. 

How The Valve Works 

Refer to the drawings in Figure 1. View “A” shows the valve in the closed 

position, held without leakage by tank pressure and the valve’s closing 

spring. Actuation of the operating handle alone does not open the valve, 

it only allows pressure to equalize between the inlet and outlet of the 

valve by rapid bleeding of the product downstream. This equalized 

pressure then allows the valve to open via the excess flow spring. 

The valve is opened by moving the handle to mid-point, see view “B”. 

This moves the actuator to the equalizing position of the valve stem in 

the pilot opening, allowing more product to bleed downstream than if the 

handle was fully open. 

In a few seconds, the tank and downstream pressure will be equalized, 

allowing the excess flow spring to push the poppet to the open position, 

see view “C”. The handle should then be moved to the fully opened 

position. 

If the handle is quickly moved to the fully opened position, the pilot valve 

allows a small amount of bleed downstream, but much less than during 

rapid bleed, view “B”. This results in a longer pressure equalizing time 

before the valve can open. 

NOTE: The poppet will not open until outlet pressure approximates 

tank pressure! 

Once the poppet is open, flow greater than the excess flow spring rating, 

or a sufficient surge in force of the flow, forces the poppet closed against 

the excess flow spring, as seen in view “D”. The pilot valve in this position 

is open and allows a small amount of bleed downstream, but much less 

than during rapid bleed, view “B”. 

When the operating handle is moved to the closed position, the valve 

closes and a tight, leakproof seal is re-established as seen in view “A”. 

Valve Installation 

The valve may be installed in a full or half coupling. 

WARNING: Do not install the valve in any piping that will restrict the 

valve inlet or outlet! 

After valve, pump and system piping are fully installed, run a thorough 

leak test using a high quality leak detection solution. The unit must be 

leak-free before being placed in service. In addition, the system must 

be tested to assure proper excess flow valve operation by simulating a 

break downstream at the furthest point being protected at the lowest 

operating pressure. 

WARNING: This test must be performed in a safe location, as 

testing with flammable gas is extremely hazardous. Only authorized 

trained personnel should perform this test. 

NOTE: To provide excess flow protection, the flow rating of the pump, 

piping, valves, fittings and hose on the inlet and outlet sides of the valve 

must be greater than the flow rating of the valve. Any restrictions that 

reduce the flow to less than the excess flow valve rating will result in the 

excess flow valve not operating when required. 

A3209TL Latch Assembly Installation 

The A3209TL Latch Assembly for use with the A3209A050, is a 

remote release mechanism employing a fuse link with a 212° F. 

melting point. Refer to Figure 2 when installing the latch assembly. 

1. Remove lever stop pin located nearest the internal valve outlet with 

an appropriate wrench. 

2. Position latch hole openings with the threaded holes in the valve and 

insert screws and washers as shown in Figure 2. Secure screws 

tightly with an appropriate wrench. 

3. Check operation by moving the lever to the open position and 

securing it with the latch. Pull latch outward to return the lever to the 


4. A cable should be run from the latch to a remote release handle. The 

cable should be taut, and may require pulleys to keep the cable from 

restricting interference that would prohibit proper operation. The 

fusible link will melt if exposed to fire or heat over 212° F. 

CAUTION: Stay clear of the valve lever as it moves to the closed 

position when unlatching. 

Cable Control System 

The cable control system employed must meet the requirements and be 

in accordance with the provisions of NFPA #58, DOT, ANSI, and all 

applicable federal, state, provincial and local codes. 

Valve Operation and Precautions 

1. Valve must be opened before starting pump, and before opening 

valve on pump outlet. 

2. Leave pumping system “wet” to avoid drying of seals and to reduce 

time involved in opening valve. Drain piping only when required by 

codes or safe operating practices. 

3. When piping is dry or at a lower pressure than the tank, open valve 

half-way for a few seconds to allow line pressure to equalize before 

fully opening the valve handle. The poppet may not open immediately 

if the handle is placed in the open position too quickly. 

4. Flow surges may close the built-in excess flow valve and should be 

avoided. If the excess flow valve slams shut; stop the pump, close 

the nearest downstream valve, and move handle to the mid-point 

position to equalize pressure until valve reopens with a click, then 

restart pump and open downstream valve slowly. 

5. Always keep valve closed except during product transfer. 

6. Completely open all valves during pumping. Partially closed valves 

may prevent excess flow valve from closing when required, even in 

a properly designed piping system. 

7. All personnel must be aware of remote closure locations and their 

operation in case of an emergency. They must also be aware of the 

equalizing opening through which bleeding can occur after the 

excess flow valve closes. If this bleed is not stopped by closing a 

downstream valve, a hazard may occur. 

Troublshooting 

1. Internal Valve Will Not Open 

Causes may be excess leakage downstream, pump engaged too 

quickly, excessive wear of the valve, or ice accumulation. 

When there is excessive volume downstream, a greater amount of 

time is required to equalize tank and downstream pressure.

To determine if the pilot seat is opening, install a pressure gauge 

downstream of valve outlet while keeping the system closed downstream 

of the pressure gauge. Open any hand valves between the 

valve and pressure gauge, and open internal valve. Pilot seat is not 

opening if pressure does not build up to tank pressure. Perform this 

test with the pump off. A broken internal part may cause the pilot seat 

not to open. 

2. Premature Valve Closure 

First, check to see that the operating lever is properly connected and 

fully opens the valve. Premature closure may also be a result of; 

engaging pump too quickly, sudden line surges, and under rated 

excess flow spring or an obstructed inlet port. 

3. Valve Will Not Close 

Usually the result of a faulty or sticking actuator. Check the actuator 

to see that it works freely by cycling it several times with the lever. If 

it sticks in the open position, repairs are required. Internal damage 

will also cause the valve not to close. 

4. Low Flow Capacity 

Downstream piping may be too small and/or long, the internal valve 

may be too small, the valve inlet may be restricted, there may be 

downstream restrictions or a bypass valve could be stuck in the open 

position. All are possible causes of low flow. 

Figure 1 – Valve Operation 

Maintenance 

Potential problems may be eliminated with preventative valve maintenance. 

Perform the following steps once a month. 

1. Check to see that the operating lever moves freely and smoothly. 

Check for leakage around the stem and sealing gland with a high 

quality leak detection solution. Leakage will require replacement of 

the sealing gland packing. A sticking lever indicates trapped foreign 

material or mechanism wear. 

2. Check both seat discs for tight closure. Close internal valve and 

exhaust downstream pressure. Be sure piping is warmed to an 

ambient temperature. Install a pressure gauge between internal 

valve and first downstream valve. Close the first downstream valve 

and observe for pressure build-up between the two closed valves 

with pressure gauge. If leakage occurs, replacement of both seat 

disc will be required. 

3. Inspect, clean and lubricate all operating controls. Check controls to 

see the they open valve fully and that they freely close the valve. Worn 

parts should be replaced. 

4. Remove valve if the tank is to be steam cleaned. Heat may damage 

the valve seals and seats. 

5. Valve is not designed for water service. After tank is hydrostatically 

tested, immediately remove all water and allow tank to thoroughly dry 

out before installing valve.

Foreword 

The A3209PA Pneumatic Actuator is designed especially for use with 

the A3209A Series Internal Valves. It is designed to provide a convenient 

means for opening and closing the valve from a remote location. 

Responsibility for proper installation must be met by the installer. 

How the Pneumatic Actuator Works 

The pneumatic actuator can be pressurized with either air or nitrogen. 

The actuator’s diaphragm rod moves the valve’s operating lever to the 

open position when pressure is applied. Upon loss of pressure, the 

valve’s operation lever returns to the closed position. The A3209PA 

operates with a minimum pressure of 50 psig and a maximum operation 

pressure of 250 psig. 

The A3209PA pneumatic actuator is compatible with existing air interlock 

systems. It also provides a convenient means of operating a 

number of internal valves on stationary storage tanks at bulk plants from 

remote locations. 


Refer to diagram below. 

1. Remove two stop pins from valve body. 

Note: If pneumatic cylinder and yoke assembly are already assembled 

to bracket, skip to step 5. 

2. Secure air cylinder to bracket by inserting the nose end through the 

hole and tightening the 5 /8" – 18 mounting nut. 

A3209PA Pneumatic Actuator 



3. Thread 5 /16" hex nut onto cylinder rod. 

4. Secure yoke connector assembly to air cylinder rod using 5 /16" hex 

nut. 

5. Install actuator bracket on top of valve with top of bracket facing up 

while sliding yoke assembly onto handle and align holes of bracket

Foreword 

The A3210A065 1 1 /4" Internal Valve is designed primarily for use with 

propane, butane and anhydrous ammonia. It is intended for use as a 

main valve on pump systems with small capacity such as a motor fuel 

dispensers. It may also be installed in the vapor return line and liquid 

withdrawal openings on trucks and in nurse tanks, provided the proper 

piping configuration is used. 

A pneumatic actuator, ECII ® # A3210PA, is available to provide a means 

of opening and closure of the valve using propane or air. The A3210PA 

requires only 10 PSIG inlet pressure for proper operation. 


Refer to the drawings in Figure 1. View "A" shows the valve held closed 

by tank pressure and the valve's closing spring. Actuation of the 

operating lever alone does not open the valve, it only allows pressure to 

equalize between the inlet and outlet of the valve by rapid bleeding of the 

product downstream. This equalized pressure then allows the valve to 

open via the internal spring. 

The valve opens by moving the operating lever to the mid-point, see view 

"B". This position allows the actuator to put the equalizing portion of the 

valve stem in the pilot opening, allowing more product to bleed downstream 

than if the lever was fully open. 

In a few seconds, the tank and downstream pressure will be nearly 

equal. The excess flow spring will push the main poppet to the open 

position, see view "C", and the lever should be moved to the fully opened 

position. 

If at first, the lever is quickly moved to the fully opened position, the pilot 

valve allows a small amount of bleed downstream, but much less than 

during rapid bleed (view "B"). This results in a longer pressure equalizing 

time before the main valve can open. 

NOTE: Main poppet will not open until outlet pressure approximates 


Once the main poppet is open, flow greater than the excess flow spring 

rating, or a sufficient surge in force of the flow, forces the main poppet 

closed against the excess flow spring, see view "D". The pilot valve in 

this position is open and allows a small amount of bleed downstream, 

but much less than during rapid bleed (view "B"). When the operating 

lever is moved to the closed position, the valve closes and a tight, 

leakproof seal is re-established as seen in view "A". 


The A3210A065 1 1 /4" Internal Valve must be installed in a modified half 

coupling or the equivalent, see Figure 2. If mounted in a half coupling, 

the inside diameter must be machined out to 1 1 /2" diameter. If used in 

a reducing bushing, the inside diameter must be machined out to 1 1 /2" 

diameter – 3 /4" to 1" of the inside thread must be left and the remaining 

portion of the inside diameter must be machined to a wall thickness of 

1 

/4", see Figure 3. 

WARNING: Do not install the valve in a full coupling or in any piping 

that will restrict the valve inlet! 


leak test on all joints using a high quality leak detection solution. The 

installation must be leak free before being placed in service. In addition, 

the system must be tested for excess flow valve operation by simulating 

a break downstream at the furthest point being protected. 




NOTE: To provide excess flow protection, the flow rating of the 

pump, piping, valves, fittings and hose on the inlet and outlet 

sides of the valve must be greater than the flow rating of the valve. 

Any restrictions that reduce the flow to less than the excess flow 

valve rating will result in the excess flow valve not operating when 

required. 


The cable control system selected must operate the valve without 

restricting free closing of the operating lever. One suggested method 

employs a simple return spring to overcome cable system friction, see 

Figure 2. 

The lever housing may be rotated 360° to accommodate actuation by 

cable from any direction. This is done by loosening the retaining screws, 

rotating the housing to the desired position, and securely re-tightening 

the screws. 

NOTE: Be sure the upper face of the lever housing is snug against 

the body shoulder when screws are tightened. 

The cable control system employed must meet the requirements and 

provisions of NFPA #58, DOT, ANSI, and all applicable federal, state, 

provincial and local codes. 

Valve Operation 



2. Leave pumping system "wet" to avoid drying of seals and to reduce 



3. When piping is dry or at lower pressure than the tank, open valve 


fully opening the valve lever. The main poppet may not open 

immediately if the lever is placed in the open position too quickly. 

4. Flow surges may close the built-in excess flow valve and must be 

avoided. If the valve slams shut, stop the pump, close the nearest 

downstream valve, and move lever to midpoint position to equalize 

pressure until valve re-opens with a click; then restart pump and 

open downstream valve slowly. 


6. Completely open all hand valves during pumping. Throttle type 

valves may prevent excess flow valve from closing when required.

valve, a hazard may occur.

time is required to equalize tank and downstream pressure. 


downstream of valve outlet, open any hand valves between valve 

and pressure gauge, and open valve. Pilot seat is not opening if 

pressure does not build up to tank pressure. Perform this test with 

pump off. A broken internal part may cause the pilot seat not to 

open. 


First, check to see that the operating lever is properly connected

and fully opens the valve. Premature closure may be a result of 

engaging the pump too quickly, sudden line surges, an underrated 

/weak excess flow spring or an obstructed inlet port. 


Usually a result of a faulty or sticking actuator. Check actuator to 

see that it works freely by cycling it several times with the lever. If 

it sticks in the open position, repairs are required. Internal damage 



Downstream piping may be too small and /or long, internal valve 

may be too small, the valve inlet may be restricted, possible 

downstream restrictions, or a bypass valve stuck in the open 

position are possible causes of low flow. 

Maintenance 

Potential problems may be eliminated with preventive internal valve 

maintenance. Perform the following steps once a month: 


There should be no leakage around the lower stem or seal housing. 

Leakage requires replacement of the seal housing packing. A 

sticking lever indicates trapped foreign material or mechanism 

wear. 

2. Check both seat discs for tight closure. Close valve and exhaust 

downstream pressure. Be sure piping is warmed to an ambient 

temperature. Close the first downstream valve and note pressure 

buildup between the two closed valves with a pressure gauge. If 

leakage occurs, replace both seat discs. 

3. Inspect, clean and oil all operating controls. Check controls to see 

that they open valve fully, but do not over travel the valve operating 

lever. See that they work freely to close the valve. Worn parts should 

be replaced. 

4. Remove valve if the tank is to be steamed cleaned. Heat may 

damage the valve's seals. 

5. Valve is not designed for water service . After tank is hydrostatically 

tested, immediately remove all water and allow tank to thoroughly 

dry out before installing valve.

Foreword 

The A3210PA-R1 Pneumatic Actuator is designed specifically for 

use with the A3210A Series 1 1 /4" Internal Valve. 

The A3210PA-R1 provides a convenient means of opening and 

closing the internal valve from a remote location, primarily in motor 

fuel dispensing applications. The actuator can be installed in 

standard actuating systems or automated dispensing systems. 

How The Pneumatic Actuator Works 

The pneumatic actuator can be pressurized with clean, dry compressed 

air. The actuator’s diaphragm rod pushes the valve’s 

operating mechanism to the open position when pressure is applied. 

Upon loss of pressure, the rod retracts and allows the valve’s 

operating mechanism to return to the closed position. 

The A3210PA-R1 operates with a minimum pressure of 40 psig and 

a maximum operating pressure of 250 psig. 


NOTE: If the manual actuator is present, it must first be removed 

before installation of the pneumatic actuator. Refer to 

Diagram 1 during removal of the manual actuator. 

1. Remove the three retaining bolts and save them for assembly of 

the pneumatic actuator. 

2. Remove manual actuator lever assembly from the internal valve 

and retain for future use. 


NOTE: Refer to Diagram 2 during assembly of the pneumatic 

actuator to the internal valve. 

1. Start the three retaining bolts in the holes in the Lever Housing. 

2. Mount the Pneumatic Actuator to the adapter using the 5 /18-18 

mounting nut supplied with the Actuator. 

3. Mount the Adapter and Actuator Assembly to the Manual Lever

"TEE" is to be supplied by customer for installation of thermal 

fuse. 

NOTE: The pneumatic actuating system employed must meet 

the requirements and provisions of NFPA #58, DOT, ANSI, and 

all applicable federal, state provincial, and local standards, 

codes, regulations, and laws. 

5. Test the actuator for proper operation and check the system for 

leaks using a high-quality leak detecting solution. 

Typical Standard Actuating System Operation 

Refer to Diagram 3 

1. When toggle valve is in the open position, ports A and B are 

open and port C is blocked, allowing the pneumatic supply to 

reach the actuator and push the valve to the open position. 

2. When the toggle valve is in the closed position, port A is blocked 

and ports B and C are open, shutting off and exhausting the 

pneumatic supply to the actuator and allowing the valve to 

move to the closed position. 

Typical Automated Dispensing System Operation 

Refer to Diagram 4 

1. The explosion-proof 3-way solenoid valve is opened and closed 

by the meter. When the meter is actuated, by a key card for 

example, contacts in the meter opening valve initiate a time 

delay sequence that starts the pump and opens the solenoid 

valve. When the meter is stopped, the pump shuts off and the 

solenoid valve closes. 

2. The system opens and closes the 3-way solenoid valve automatically 

and the remaining operation follows steps one and 

two in the standard system sequence. 

NOTE: Plastic pneumatic line is recommended between the 

actuator and toggle valve to provide for some amount of 

thermal protection in case of a fire. However, a thermal fuse is 

required for adequate protection. The line should melt and 

exhaust the pneumatic supply to the actuator allowing the 

valve to go to the closed position.

Foreword 

The A3212TL Thermal Latch is designed especially for use with the 

A3212A Series Internal Valves. It is designed to provide thermal 

protection for the internal valve installation. Responsibility for 

proper installation must be met by the installer. 

How The Thermal Latch Works 

When the valve’s operating lever is moved to the open position, the 

latch automatically holds the lever open. If exposed to fire or 

extreme heat, the built-in fusible element is designed to melt and 

return the operating lever to the closed position. It is designed to 

release when temperature reaches 212° F.

Thermal Latch Installation — Refer to diagram below. 

1. Attach latch support to internal valve using the two socket head 

cap screws, placing washers between latch support and internal 

valve. 

2. Insert a shoulder socket head screw through one of the two 

holes located on end of latch support and secure with hex nut. 

(Try the hole on the end of the bracket first to achieve maximum 

opening of the valve.) 

3. Attach latch to lever with a shoulder socket head screw taking 

care to orient latch as shown in diagram. Place spacer in 

between latch and lever, aligning holes. Place shoulder socket 

head screw through holes as shown and tighten securely.

Series Internal Valves 





Foreword 

The A3212R , A3212RT, A3213A, and A3213T Series Internal Valves 

are designed primarily for use with propane, butane and anhydrous 

ammonia. They are intended for use as a main valve on pump systems. 

They may also be installed in the vapor return line and liquid withdrawal 

openings on trucks or in-line installations. 

How the Valve Works 

1 Fully Closed

Closing Spring 

In the fully closed position, the valve 

is held closed without leakage by 

tank pressure and the valve’s closing 

spring. 

3 Fully Open 

In a few seconds, the tank and downstream pressure will be 

equalized, allowing the excess flow spring to push the poppet to 

the open position. The handle should then be moved to the fully 

opened position. 

If the handle is quickly moved to the

NOTE: The poppet will not open 

until outlet pressure approximates 


➱ 

➠ 

➯ 

2 Rapid Bleed 

Actuation of the operating handle alone does not open the valve, 

it only allows pressure to equalize between the inlet and outlet of the 

valve by rapid bleeding of the product downstream. This equalized 

pressure then allows the valve to open via the excess flow spring. 

The valve is opened by moving the 

Rapid Bleed 

handle to mid-point. This moves 

the actuator to the equalizing 

position which allows product to 

bleed downstream. 

The equalizing position allows more 

product to bleed downstream than 

if the handle was fully open. 

➱ 

➯ 

4 Excess Flow Closed 

Once the poppet is open, flow greater than the excess flow spring 

rating, or a sufficient surge in force of the flow, forces the poppet 

closed against the excess flow spring. The pilot valve in this position 

is open and allows a small amount of bleed downstream, but much 

less than during rapid bleed. 

When the operating handle is 

Limited 

moved to the closed position, the 

Bleed 

valve closes and a tight, leakproof 

seal is re-established as seen in 

Step 1.

The A3212R, A3212RT, A3213A, and A3213T Series can be installed 

in either half or full couplings. However, the closing rate of the excess 

flow feature of the valve will be affected by the couplings. See the closing 

flow information listed in the table below. 

The valves are designed with a break off section below the inlet pipe 

thread which is intended to shear off if the valve is struck from the side, 

leaving the valve seat intact. 

WARNING: Do not install the valve in any piping that will restrict 

the valve inlet or outlet! 

Verify that the CAM is in the correct position (see figure) before installing 

downstream piping.

trained personnel should perform test. 


pump, piping, valves, fittings and hose on the inlet and outlet sides

The cable control system should be installed in accordance with the 

provisions of NFPA 58, ANSI, DOT, and all applicable federal, state, 

provincial and local codes. 

It is suggested that an external return spring be used when utilizing a 

cable system in order to overcome any drag in the control linkage. 

Inspect the cable system for binding that could cause the valve to stick 

in the open position. 

Thermal Latches 

Thermal Latches are designed to automatically hold the Internal Valve’s 

operating lever open when the lever is moved to an open position. If 

exposed to fire or extreme heat, the built-in fusible element is designed 

to melt and return the operating lever to the closed position. 

Pneumatic Actuators 

Pneumatic Actuator Systems provide a convenient means for opening 

and closing the internal valve from a remote location. Actuators utilize 

either air or nitrogen and are compatible with existing air interlock 

systems. They can be used to operate several Internal Valves on 

stationary storage tanks and can work in conjunction with Emergency 

Shut-off Valves.

Potential problems may be eliminated with preventative valve maintenance. 

Perform the following steps once a month.

Foreword 

The A3213TL Thermal Latch is designed especially for use with 

the A3212R, A3212RT, A3213A & A3213T Series Internal Valves. 

It is designed to provide thermal protection for the internal valve 

installation. Responsibility for proper installation must be met by 

the installer.

for A3212R, A3212RT, A3213A & A3213T 

Series Internal Valves 

How the Thermal Latch Works 

When the valve’s operating lever is moved to the open position, the 

latch automatically holds the lever open. If exposed to fire or extreme 

heat, the built-in fusible element is designed to melt and return the 

operating lever to the closed position. It is designed to release when 

temperature reaches 212° F. 

Thermal Latch Installation — Refer to diagram below 

1. Position spacer between latch and internal valve. 

2. Secure assembly with screw. 

3. Install short shoulder screw in top hole of lever. 

4. To engage latch: Rotate lever and latch assembly until notch in 

latch connects on shoulder screw.

Foreword 

The A3217F Series 3" Flanged Internal Valves are designed primarily 

for use with propane, butane and anhydrous ammonia. 

The valve can be used on bobtail delivery trucks, transports and 

stationary storage tanks with flanged pumps or piping. It may be 

operated manually, by cable or with air. 


Refer to the drawings in Figure 1. View “A” shows the valve held closed 

without leakage by tank pressure and the valve’s closing spring. 

Actuation of the operating handle alone does not open the valve, it only 

allows pressure to equalize between the inlet and outlet of the valve by 

rapid bleeding of the product downstream. This equalized pressure 

then allows the valve to open via the internal spring. 

The valve opens by moving the handle to mid-point, see view “B”. This 

position allows the actuator to put the equalizing portion of the valve 

stem in the pilot opening, allowing more product to bleed downstream 

than if the handle was fully open. 



position, see view “C”, the handle should then be moved to the fully 

opened position. 

If at first, the handle is quickly moved to the fully opened position, the 

pilot valve allows a small amount of bleed downstream, but much less 

than during rapid bleed ,view “B”. This results in a longer pressure 

equalizing time before the main valve can open. 

NOTE: The main poppet will not open until outlet pressure 

approximates tank pressure! 

Once the main poppet is open, flow greater than the excess flow rating, 

or a sufficient surge in flow, forces the main poppet closed against the 

excess flow spring, as seen in view “D”. The pilot valve in this position 

is open and allows a small amount of bleed downstream, but much less 

than during rapid bleed ,view “B”. 


closes and a leak-tight seal is re-established as seen in view “A”. 


A 3" 300 lb. ANSI RF flange with a modified bore of 4 5 /8" diameter and 

5 3 /4" RF must be installed in the tank. New studs and nuts are also 

recommended. Be sure flange is clean, smooth and free of imperfections 

before valve installation. Coat the full length of the studs with an 

anti-seize compound to prevent rusting and provide for easy removal 

of the valve for maintenance. 

Place gasket with larger Interior Diameter on top flange of valve body 

to seal against tank opening. 

NOTE: The screen should be removed if the valve is to be used 

for both filling and withdrawal service or for filling alone. 

Support and position valve under flange opening of tank in its installation 

position. Be sure that: 

a) the handle is in a fully operable, convenient position and free of all 

obstacles, and that 

b) the handle is oriented in the proper direction to accommodate 

controls. 

Carefully insert valve into flange opening and onto the studs. Tighten 

two opposite nuts and bring valve flush to flange with gasket in place 

in groove – see Figure 2. In sequence, start six remaining nuts and 

tighten all nuts securely, side-to-side and alternately. 

Place gasket with smaller Interior Diameter on bottom of lower flange 

before connecting pump or mating flange. 

A hydrostatic relief valve need not be installed between the A3217F 

and next adjacent shut-off valve as excessive line pressure is automatically 

relieved by the internal valve into the tank.

3. Internal Valve Will Not Close 

Usually a result of faulty or sticking actuator. Check actuator to see 

that it works freely by disconnecting it from valve handle and cycling 

it several times, before disassembling valve. Also, operate valve 

handle manually. If it sticks in the open position, replace the 

packing and bushings. This should free the operating mechanism 

providing the valve has no internal damage. 


Downstream piping may be too small and/or long, screen or strainer 

may be plugged, possible restriction downstream, or a bypass valve 

stuck in the open position are causes of low flow. Also, the bypass 

valve may be set too low and is prematurely opening. See Technical 

Guide 102 for troubleshooting procedures. 

Maintenance 

Potential problems may be eliminated with preventive maintenance on 

the valve. Perform the following steps once a month: 

1. Check to see that the operating handle moves freely and smoothly. 

Check shaft-bonnet nut for leakage with high quality leak detection 

solution. Leakage requires replacement of the bonnet packing. A 

sticking handle may indicate trapped foreign material or mechanism 

wear. Replacement of shaft seals, shaft bushings and/or 

stem bushings may be necessary.

Foreword 

The A3219F 4" Flanged Internal Valve is designed primarily for use with 

propane, butane and anhydrous ammonia. This valve can be used on 

DOT MC331 pressure vessels and stationary storage tanks. 

Use of the A3219F Remote Thermal Release is suggested to provide a

A 4" 300lb. ANSI RF flange with a modified bore of 5 7 /8" diameter and 

7" RF must be installed in the tank. New studs are also recommended. 

Be sure flange is clean, smooth and free of imperfections before valve 

installation. Coat the full length of studs with an anti-seize compound to 

prevent rusting and provide for easy removal of valve for maintenance. 

Coat larger o-ring seal liberally with #11550-215 lubricating grease or 

equivalent, and place securely in groove of valve body. 

Support and position valve under flange opening of tank in its installation 

position. Be sure that: 

a) Handle is in fully operative, convenient position free of all obstacles, 

and that: 

b) Handle runs approximately with the width of the tank to provide for 

cable attachments to front and back of tank. (See Figure 2) 

Carefully insert valve into flange opening and onto the studs. Tighten 

two opposite nuts and bring valve flush to flange with O-ring in place 

in groove (see Figure 3). Tighten all nuts side to side and alternately.

downstream of valve outlet, open any hand valves between valve 

and pressure gauge , and open valve. Pilot seat is not opening 

if pressure does not build up to tank pressure. Perform this test 

with pump off. A broken internal part may cause pilot seat not to 

open. 

If operating handle rotates past the full open 90 degrees position, 

there is internal malfunctioning, and the valve must be disassembled 

and repaired. 

II. Premature Valve Closure. 

First, check to see that operating lever is properly connected and fully

opens valve. Premature closure may also be a result of engaging 

pump to quickly, sudden line surges, an under rated excess flow 

spring or an obstructed inlet port. 

III. Valve Will Not Close. 

Usually a result of a faulty or sticking actuator. Check actuator to 

see that it works freely by disconnecting it from valve handle and 

cycling it several times, before disassembling valve. Also, operate 

valve handle manually, if it sticks in the open position, replace the 

packing and bushings. This should free the operating mechanism 

providing the valve has no internal damage. 

IV. Low Flow Capacity. 

Downstream piping may be to small and/or long, screen or strainer 

may be plugged, possible restriction downstream, or a bypass valve 

stuck in the open positions are causes of low flow. Also, the bypass 

valve may be set too low and prematurely opening. Check for high 

differential pressure across the valve for malfunction. If valve is open, 

the differential should not exceed 5 or 6 psig. 

Maintenance 

Potential problems may be eliminated with preventive maintenance on 

the valve. Perform the following steps once a month: 

1. Check to see that the operating handle moves freely and smoothly. 

Check shaft-bonnet nut for leakage with high quality leak detection 

solution. Leakage requires replacement of the bonnet packing. A

FOREWORD: 

The A3219FPA Pneumatic Actuator is designed for use with the 

A3219F600 Series 4" Flanged Internal Valves. 

The A3219FPA provides a convenient means of opening and closing the 

internal valve from a remote location on DOT MC331 pressure vessels and 

stationary storage tanks. 

HOW THE PNEUMATIC ACTUATOR WORKS: 

The pneumatic actuator can be pressurized with either air or nitrogen. The 

actuator’s diaphragm rod moves the valve’s operating lever to the open 

position when pressure is applied. Upon loss of pressure, the valve’s operating 

lever returns to the closed position. 

The A3219FPA operates with a minimum pressure of 50 psig and a maximum 

operating pressure of 150 psig. 

The pneumatic actuator is compatible with existing air interlock systems. 

It also provides a convenient means of operating a

Foreword 

The A3219RT is designed especially for use with Internal Valves installed 

in DOT MC331 pressure vessels. The A3219RT provides a remote 

means of mechanical closure along with thermal protection by DOT 

MC331. Proper installation is the responsibility of the installer. 

DOT MC331 for emergency discharge control states: 

"On a tank over 3,500 gallons water capacity, each internal shut-off 

valve must be provided with remote means of automatic closure, 

both mechanical and thermal, that are installed at the ends of the 

tank in at least two diagonally opposite locations." 

For some installations, the thermal release may be connected to all 

internal valves of the vessel to allow them all to close at one time. 

How It Works 

The spring loaded thermal release is connected by cable to the internal

valve(s) on the vessel. In the event of extreme heat (over 212 ° F), 

the fuse link will melt, causing the spring to contract and pull the cable. 

When properly installed and unobstructed, the cable will trip the internal 

valve release lever(s) allowing the connected handle(s) to move to the 


In addition, merely yanking the cable at any point in its exposed length 

can trip the release level for remote mechanical closure.

• Return springs, if required 

Assembly and Installation 

1. Mount brackets in convenient position to vessels' fenders, clips, 

braces, etc.... DO NOT MOUNT TO TANK SHELL OR HEAD. Mount 

with open side facing down and shorter edge facing out. Leave 1" 

space between bracket and wall to allow for painting and to prevent 

rust and corrosion due to build-up of foreign material. Suggest use 

of four 7 /16" bolts with spacers. 

NOTE: Mount at least two remote thermal releases in diagonally 

opposite locations in accordance with DOT MC331, see Diagram 1. 

2. Place pins in bracket so grooves set in the bracket holes and keep 

pins in place. 

3. Assemble on end of spring to center groove of pin furthest from 

center of vessel, see Diagrams 2 & 3. 

4. Engage one end of 8" connecting chain, then fuse link to the other 

end of spring. Assemble "S" hook to fuse link, see Diagram 2. 

5. Pull "S" hook to extend spring and engage "S" hook onto center 

grove of second pin, see Diagram 2. 

NOTE: The fuse link should be visible in round window of bracket once 

assembled, see Diagram 4. 

6. Attach stainless steel cable to other end of connecting chain 

using thimbles and two heavy duty cable clamps. Attach other 

end of cable to internal valve(s) in the same manner, see 

Diagram 2 & 3. 

NOTE: Be sure cable has some slack, but not excessive. When the 

fuse link melts and the spring contracts, the cable must release the 

valve handle(s) and allow the valve(s) to close. A supplemental 

return spring may be required if heavy cable with excessive friction 

is used.

Operating Instructions 

These instructions must be included with other tank operating 

instructions. 

Chek-Lok Excess Flow Valves 

ECII ® Chek-Lok excess flow valves are designed to provide a convenient 

means of withdrawing liquid from stationary tanks prior to moving the 

tank. These valves are not intended for permanent liquid withdrawal 

installations. They allow for compliance with NFPA Pamphlet 58 standards 

which state that every container with more than 125 gallons water 

capacity built after July 1, 1961, has a connection for liquid evacuation, 

at least 3 /4" NPT size, and that every container designed for stationary 

use contains no more propane than 5% of their water capacity during 

transportation. 

Chek-Lok Adapters 

It is recommended that these brass adapters (7572C-14A and 

7572C-15A) should be connected to ECII ® Chek-Lok excess flow 

valves to open the check mechanism properly. A built-in nylon 

gasket provides a gas-tight seal. 

CAUTION: Wear approved protective gloves and eye protection 

when working with Chek-Loks. Do not vent LP-Gas near possible 

sources of ignition. 

Use an ECII ® 7550P angle valve with an ECII ® adapter 7572C- 

14A ( 3 /4" NPT female connection) or 7572C-15A ( 3 /4" NPT male 

connection). Use an ECII ® 7550P without an adapter in an 

emergency only. 

7572FC & 7580FC 

Chek-Lok ® 

Excess Flow Valves 

To Put Chek-Lok In Service 

1. Use an ECII ® 7550P angle valve or assemble a suitable capacity shutoff 

valve such as an ECII ® A7505AP, A7506AP or 7705P to ECII ® 

adapters (see below). 

2. Loosen 8594-3A plug to vent accumulated LP-Gas from Chek-Lok. 

If venting does not stop, retighten plug and use other approved 

means to withdraw liquid. 

NOTE: Use a suitable size wrench to remove cap and adapter so as 

to not remove Chek-Lok from tank at the same time. 

3. Close shut-off valve to permit excess flow valve to open. 

4. If for some reason the Chek-Lok does not open after following this 

procedure, then it is a simple matter to equalize pressures by 

introducing vapor pressure from the vapor return valve on top of the 

tank to the downstream side of the Chek-Lok or by pumping liquid 

back through the Chek-Lok. 

To Re-Lock Chek-Lok 

1. Tank pressure must be in excess of 35 PSIG. 

2. Close shut-off valve and disconnect hose or piping. 

3. Open shut-off valve fully. Liquid discharging to atmosphere should 

cause the excess flow valve to close, provided tank pressure is 35 

PSIG or more. If, for any reason, the excess flow valve does not 

close, the shut-off valve must be closed immediately and must not 

be removed until the system can be evacuated and the unit repaired. 

4. After the excess flow valve closes, remove ECII ® adapter or pipe 

nipple to which shut-off valve is attached. 

5. Clean face of Chek-Lok and install 8594-3A plug with 8594-1A 

gasket. 

IMPORTANT: Use only 8594-3A plug. Do not use standard pipe plug. 

Chek-Lok Mounting 

ECII ® Chek-Lok valves may be bottom mounted or top mounted with 

a dip tube. For bottom mounting, it is preferable to position the coupling 

in the shell or head, slightly off bottom, to avoid accumulation of sludge, 

etc..., around the check valve which could affect the proper operation 

of the excess flow valve.

Chek-Lok ® Application 

Chek-Lok Valves are designed to provide a convenient means of 

withdrawing liquid from stationary containers prior to moving the 

container. 

NFPA Pamphlet 58 standards require: 1) containers with 125 gallons 

water capacity or more have a connection for liquid evacuation which 

is at least 3 /4" NPT, and 2) containers designed for stationary use, to 

have no more propane than 5% of their water capacity in liquid form 

during transportation. These rules apply to containers manufactured 

after July 1, 1961. 

These Chek-Lok Valves may also be used on permanent installations 

provided the excess flow valve is sized properly for the system and 

piping. Note: In some cases, it may be necessary to install an in-line 

excess flow valve to protect the downstream piping.

in the shell or head, slightly off bottom, to avoid accumulation of sludge, 

etc..., around the check valve which could affect the proper operation 

of the excess flow valve. 

Proper Use of Chek-Lok ® 

Chek-Lok Adapters – You must use an ECII ® 7590U-10 Adapter 

to connect to an ECII ® 7590U or 7591U Chek-Lok. This insures 

a proper connection to open the check mechanism. A built-in 

nylon gasket provides a gas tight seal. 

Shut-Off Valves – The Chek-Lok is designed to be used with 

an ECII ® 7550P angle valve or an equivalent capacity shut-off 

valve. 

Instructions to Open Chek-Lok ® 

NOTE: Use a suitable wrench when removing the cap and adapter from 

the Chek-Lok. Do not allow the Chek-Lok to un-thread from the tank 

during removal. When necessary, use a second wrench to secure the 

Chek-Lok in position. 

1. Loosen the 7590U-5 cap to vent any accumulated LP-Gas from the 

Chek-Lok. After venting stops, remove the cap. 

If venting does not stop, retighten the cap and use other approved 

means to withdraw liquid from the container. 

2. Before beginning withdrawal, securely connect an ECII ® 7550P 

angle valve or suitable shut-off valve to the 7590U-10 adapter. 

3. Fully open the shut-off valve – the valve’s handwheel must be fully 

opened before connecting adapter to tank.

4. Completely thread the adapter and shut-off valve assembly onto 

the Chek-Lok by turning adapter’s coupling nut clockwise until it 

is tight. 

Immediately close the shut-off valve. Listen for an audible click to 

signal that the Chek-Lok has opened and is actuated for liquid 

withdrawal. 

5. Check the coupling nut and adapter assembly for leaks using a 

suitable leak detection solution. 

6. If the Chek-Lok fails to open after following this procedure, the 

pressure downstream of the shut-off valve should be increased to 

equalize pressure in the Chek-Lok. 

It is simple to equalize pressures using vapor from either the vapor 

return valve or service valve, or from a hose end valve connected 

to the delivery truck. 

Instructions to Close Chek-Lok ® 

1. Tank pressure must be in excess of 35 PSIG. 

2. Close shut-off valve and disconnect the hose or piping. 

3. Open shut-off valve fully. Liquid discharging to the atmosphere 

should cause the excess flow feature of the Chek-Lok to close, 

provided tank pressure is 35 PSIG or more. If, for any reason, the 

excess flow valve does not close, the shut-off valve must be closed 

immediately and must not be removed until the system can be 

evacuated and the unit repaired. 

4. After the excess flow valve closes, remove the Adapter and 

Shut-Off Valve Assembly. 

5. Clean face of Chek-Lok and install the 7590U-5 Cap with a 

8594-1A Gasket. 

IMPORTANT: Only use the 7590U-5 Cap. Do not use a standard 

pipe cap.

Operation Instructions for the 7590U-20 

NOTE: Use of an appropriate 3 /4" shut-off valve with 

the 7590U-20 Adapter is recommended. The shut-off 

valve should be installed between the outlet of the 

Adapter and the unloading hose. 

Unloading operations should be performed only by 

thoroughly trained and qualified personnel. 

Opening 7590U or 7591U Chek-Lok ® with the 

7590U-20 Adapter 

NOTE: Use a suitable wrench when removing the cap 

and Adapter from the Chek-Lok ® . Do not allow the

4. Connect an unloading hose to the outlet of the Adapter or to the Adapter 

and shut-off valve assembly installed onto Chek-Lok ® Valve. 

5. Close the shut-off valve at the tank end of unloading hose. If a shut-off 

valve is connected to the outlet of the Adapter, also close this valve. 

6. Turn lever to DOWN & OPEN position. This allows flow through Adapter. 

WARNING: If the lever does not completely reach the full DOWN & OPEN 

position, the equalizing stem may have already been fully opened. Do 

not force the lever down further. Forcing the lever will damage the 

equalizing stem and seat assembly. This could prevent proper contact 

between the seat assembly and the seat when closing the Adapter – 

resulting in leaks and the free flow of liquid or vapor through the Adapter. 

7. Equalize pressure in the Adapter and Chek-Lok ® . This allows the excess 

flow check mechanism in the Chek-Lok ® Valve to open – necessary for 

evacuation. 

• To equalize pressure when a 3 /4" shut-off valve is connected to the 

Outlet of Adapter: 

Be sure shut-off valves at adapter outlet and tank are closed. It 

should take approximately 20 to 30 seconds to equalize pressure. 

After pressure is equalized, slowly open the 3 /4" shut-off valve at the 

adapter outlet to pressurize the unloading hose. 

• To equalize pressure when a 3 /4" shut-off valve is not connected to the 

Outlet of Adapter: 

Be sure the shut-off valve at the tank is closed. It may take several 

minutes to equalize pressure between the Chek-Lok ® and the 

unloading hose.

Typical Installation – Figure 1 

The 7605B is a "swing chek" design which uses spring force PLUS 

differential pressure to assure fast, positive valve closure. An arrow is 

cast into the top of the valve to indicate flow direction. The "swing chek" 

closes with the flow. The arrow must point in the direction of flow when 

the valve is installed (usually to the hose connection). 

The valve must be installed horizontally on the plant side of the bulkhead 

in the fixed piping of the transfer system within 20 feet (of lineal pipe) 

from the nearest end of the hose or swivel type piping to which the hose 

or swivel type piping is connected. If the valve is installed more than 

5 feet from this hose end connection, a supplemental, temperaturesensitive 

closing device (7606RT) must be installed within 5 feet of the 

hose end connection.

1. Raise operating lever to open valve. The latch will engage in this 

position. 

2. Pull upper latch release to the left to close valve. 

3. Reopen valve, push the lower latch release to the right to close valve. 

4. Check Installation: (a) close hose end valve; (b) open ESV; (c) charge 

system with LP-Gas; and (d) check all connections for leakage. 

Important: The ESV is a full flow "swing chek" type valve. It will open 

with nominal manual effort if LP-Gas pressure is on both sides of the 

check. If the ESV is closed with LP-Gas pressure behind the check only, 

the opening effort is greater and the following procedure must be used: 

Raise operating lever slightly. (A considerable pull will be 

required at high differential pressure). This opens the equalizing 

valve built into the valve check; wait until the LP-Gas pressure 

has equalized across the valve seat and the ESV will open with 

nominal manual effort.

Purpose 

Provides continuous operation of the emergency shut-off valve 

control system in spite of small leaks in tubing joints, cylinders, 

etc. A small (#80 drill) orifice is provided to compensate for such 

leaks — keeping the system charged and allowing the emergency 

shut-off valve(s) to remained latched open during operation. 

Opening the emergency valve(s) will exhaust the pressure in the 

control system, allowing the cylinder to release the emergency 

shut-off valve latch. 

Shut-off the control gas supply whenever a shut down occurs or 

the ESV system is not in operation. This will conserve control gas 

supply.

greater distances. Note: Do not attempt to connect in series two 

or more remote devices because the fixed stroke lengths will be 

absorbed by the take up inherent in the system. Do not attempt 

to connect more than one ESV to the remote device. 

NOTE: The remote unit should be mounted in a vertical position, 

as shown in Figure 1. 

A 1" NPT threaded bottom connection is provided for mounting. A 1" 

NPT floor flange with a riser pipe will provide a pedestal for attachment, 

or a 1" pipe coupling welded to a structural support can also be used. 

If the desired location for installing the remote unit is in an open area 

then a 1" riser pipe sunk in a concrete pad can be used.

Cable Connection – Figure 2 

Stainless steel cable (aircraft type) 1 /16" diameter with 7 x 7 stranding 

is required. This type of cable is pliable and will make terminal loop 

connections easier to form. 

It will be necessary to provide a support for the cable to prevent slack. 

Any connection from the remote unit to the ESV longer than 3 feet will 

require some type of support. Conduit is satisfactory if it is inspected 

regularly to make sure cable is free to move at all times. Other types 

of support can be used if conduit is not desired. 

1 

/2" thin wall electrical conduit is readily available. There are many types 

of fittings and clamps that can by used with 1 /2" conduit. Figure 2 

shows how conduit can be conveyed along pipelines by using standard 

pipe hangers. 

After erecting cable support make the cable terminal connections as 

follows: 

Step A: At the remote unit make a loop sleeve connection through 

the eye of the turnbuckle. 

Step B: Make a loop sleeve connection to the valve. 

With the ESV closed, the turnbuckle should be adjusted to provide only 

the amount of tension required to prevent sag in the cable. 

Caution: Cable should be snug but not tight enough to unlock the 

valve latching mechanism when in the closed position.

Foreword 

The 7606RM Remote Cable Release Kit has been specifically designed 

for versatile, multi-directional manual control of your ESV system. 

Cable arrangements can easily be adapted to your specific needs, 

allowing lines of control from 3 or more directions. The kit even permits 

remote release actuation from outside the fenced area of the average 

bulk plant. Two or more ESVs can be operated simultaneously with 

a single control. 

When installed, the entire control system remains exposed for flexibility 

and dependability. Pulleys are not required to change directions; nor 

is there need to run the cable through conduit or tubing which could 

cause friction or freeze up in bad weather. 

Extra cable clamps, etc. are available for more elaborate systems.

• 1" Standard weight tees for cable guides, as needed. 

• 1" Standard weight caps for terminal posts, as needed. 

• Concrete for setting posts. 

• Good quality cable cutter. 

• Vise grip wrench for cable clamp installation. 

Installation Procedure 

1. Make a sketch of your plant layout, and determine where the terminating 

points of the remote manual release system should be. At least two 

remote cable lines going in two directions should be provided, in order 

to assure that one line will be approachable regardless of wind 

direction. Then, plan the cable system according to the suggestions 

herein, paying particular attention to how the cables are connected 

between primary and secondary lines of control (see figure 5). 

2. Install terminal posts and support posts as required. Support posts should 

be placed along primary and auxiliary lines approximately 15 feet apart. 

3. Install cable system, complete with tension spring (see figure 1 and 2). Adjust 

as necessary to provide proper shutdown action from all remote locations. 

7606RM Remote Manual 

ESV Cable Kit Installation 

Instructions 

4. Thoroughly test system by actuating several times, and make further 

adjustments as necessary. 

5. Complete system should be operated frequently, and adjusted wherever 

necessary to keep it in ready condition. 

6. It is recommended that a routing daily test procedure be established 

for your ESV system, as well as all other safety related equipment in 

the plant. 

Description of Control 

1. The basic 7606RM Cable Control System is installed as shown in Figure 

1. The primary cable (A) is stretched from the ESV location (B) to the 

terminal post (C), and is held taut by the tension spring (D). 

2. A short length of cable (E) is attached to the ESV latch release by means 

of an S-hook (F) (see Figure 3) and to the primary cable with a quick 

link (G), leaving a slight amount of slack to prevent premature closing 

of the ESV. The other end of the tension spring is attached to another 

terminal post (H), or directly to the piping or bulkhead by means of a 

simple cable linkage (see Figure 2). 

3. Support post (J) are mounted approximately 15 feet apart along the 

primary cable to prevent excessive whipping in severe windy conditions, 

and to help support the weight of the cable for extremely long runs. 

Instruction signs (K) are attached to the cable, plant fence or other 

suitable support in prominent locations. 

NOTE: If signs are installed on cable, they should be secured close to 

support posts, or terminal posts. 

4. Final adjustment of the cable system is provided by the turnbuckle (L). 

5. Pulling on the primary cable (A) at any point in its length will tighten and 

pull the short length of cable (E), pulling the ESV latch release to instantly 

close the emergency shut off valve. Letting the primary cable go will 

allow the ESV to be manually reopened. 

Description of Auxiliary Control 

1. Auxiliary release cables may be installed along the primary cable (A) 

at any point 3 feet or more from the quick link (G) or turnbuckle (L) 

(see Figure 4). 

2. An auxiliary post (M) is installed and a short cable (N) about 12 inches 

long is attached between the post and the primary cable as shown. 

The auxiliary release cable (O) is attached at right angles to the primary 

cable and run to terminal post (P), using support post (Q) as required. 

3. Adjust length of auxiliary cable (O) to eliminate slack, but do not pull 

primary cable out of alignment. For very long auxiliary cables, it may 

be necessary to add a tension spring attached to another terminal post 

to hold it taut without affecting primary cable. 

4. Simply reverse the arrangement in Figure 4 to add an auxiliary release 

cable on the other side of the primary cable (A). 

5. Place separate auxiliary release cables at least 2 feet apart. 

6. Many variations of arrangements shown are possible by applying the 

basic ideas shown in Figures 1 through 5 to meet individual needs. Call 

ECII or your Authorized Product Distributor if you need advice. 

Hints for Installation 

1. Cut cables carefully and square for easy installation of cable clamps. 

2. Squeeze clamps tightly with vise grip pliers or other tools to attach them 

securely to cable. Check each clamp to make sure it doesn’t slip. 

3. Don’t kink cables when handling. Unwind coils carefully. A kinked cable 

will act as a spring, making it difficult to properly adjust control systems. 

4. Squeeze each loop flat with fingers after clamping cables, to remote 

excessive spring action. This will make it easier to adjust the

5. Install the support post accurately, in line with cable runs, to minimize 

friction and eliminate possible cable wear. 

6. It’s much better to keep the entire cable installation above ground. 

Try to avoid the necessity of crossing a driveway or walk area. If a 

driveway or walk area must be crossed, consider going over, rather 

than under. An alternate choice in such situations would be a 

pneumatic system. 

7. Mount all terminal posts and guide posts in concrete for a permanent, 

sturdy installation. 

NOTE:It is recommended that all ESVs use a transfer hose cable control 

as the first line of defense. Specify Part Number 7609-50. Use it even 

for applications not incorporating a permanently attached hose by 

attaching cable to truck end of break away fitting or piping.

Operation 

The 7606RT Remote Thermal Cable Kit is used with ECII ® Emergency 

Shut-Off Valves (ESVs) to provide automatic temperature actuated 

shutdown from a remote location. They are needed to comply with 

NFPA #58 requirements when the Emergency Shut-Off Valve is installed 

more than five feet from the nearest end of the hose or swivel type piping 

connected to the line in which the valve is installed. 

Other applications include automatic temperature actuated shutdown 

of Emergency Shut-Off Valves used to shut off flow in event of fire in 

vaporizer, cylinder filling, or motor fuel dispenser applications. 

Installation 

1. Make a sketch of bulkhead area. Determine desired location for 

remote thermal release. It is best if cable (50 ft. maximum length) can 

be run in a straight line parallel to axis of ESV, as shown in Figure 1, 

directly to remote thermal release. If change in direction is required, 

see Figure 2. 

2. Install 1" pipe terminal post (G) or other suitable mounting means at 

desired location for remote thermal release. Install 1" pipe support 

posts (H) with 1" tees as needed, approximately 15 feet apart along 

cable line. 

3. Install 1" coupling on top of terminal post and mount thermal release 

assembly, with fuse link end facing directly towards where the cable 

will run. 

4. Attach cable (D) to end of chain, (C) with use of sleeve loop. Attach 

other end of cable to forward release lever of ESV (E) with a sleeve 

loop, adjusting cable length tight enough to eliminate excessive 

slack, but loose enough to prevent premature closing of ESV. 

7606RT Remote Thermal 

Cable Kit Installation Manual 

NOTE: For long runs, or if a change of direction in control line is needed, 

install Part 7606RM-1 Tension Spring to prevent premature closing of 

ESV. (Refer to ECII ® Instruction Sheet 7606RM-301 for the 7606RM 

Remote Manual ESV Cable Kit.) 

5. Test operation of completely assembled system to assure ESV will 

close properly when fuse link (B) actuates. This may be done by 

rotating ESV lever to open and latched position. Then pull carefully 

on chain (C) to stretch spring enough to remove fuse link (B) from end 

loop of spring. Relax pull on chain, allowing spring (A) to pull cable 

(D). ESV should close as cable (D) tightens. Repeat this several times 

to assure that ESV will close properly. Reinstall fuse link, pulling chain 

to stretch spring as needed. 

NOTE: If remote thermal release cable must turn a corner, use a 12" 

cable loop and terminal post as shown in Figure 2. The 12" cable loop 

will swing in an arc when thermal release spring pulls cable, applying 

tension to cable attached to ESV to close valve. 

Many variations from arrangements shown are possible. Apply the 

basic ideas shown in Figures 1 and 2 to meet individual needs. Please 

call us if you need advice. 

Hints for Installation 

1. Cut cables carefully and square for easy installation of cable clamps. 

2. Squeeze clamps tightly with vise-grip pliers or other tool to attach 

them securely to cable. Check each clamp to make sure it doesn’t 

slip. 

3. Don’t kink cables when handling. Unwind coils carefully. A kinked 

cable will act as a spring, making it difficult to properly adjust control 

systems. 

4. Squeeze each loop flat with fingers after clamping cables, to remove 

excessive spring action. This will make it easier to adjust the 

completed system and minimize later readjustment. 

5. Install the support posts accurately, in line with cable runs, to 

minimize friction and eliminate possible cable wear. 

6. Keep the entire cable installation above ground. 

7. Mount terminal post and all guide posts in concrete for a permanent, 

sturdy installation. 

NOTE: It is recommended that all ECII ® ESVs use Part 7609-50 Transfer 

Hose Cable Control as the first line of defense. Use it even for 

applications not incorporating a permanently attached hose, by attaching 

cable to truck end of breakaway fitting or piping.

The 7609-50 contains 20 feet of cable for connecting an emergency 

shut-off valve to the downstream loading hose. Cable-to-hose 

straps and a stainless steel clamp are provided to secure the cable 

end to the hose. 

NOTE: The thermal-element to operate the emergency valves 

should be not more than 5 feet from the nearest end of the hose. 

Installation 

See figure below 

1. Make a loop connection with end of cable to the latching arm or 

valve pull lanyard using a loop sleeve contained in this kit.

Cable Kit 

Installation Instructions 

2. Run cable parallel to piping up to a point where the cable can now 

be angled towards the nearest end of the hose. A guide such as an 

eye bolt, or a single sheave pulley will be required to change the 

direction of the cable. 

3. Clamp cable with a nylon-bundle-tie to the hose immediately next 

to fixed piping or swivel type connection. From this point back to the 

valve, the cable should be taut but not strained. To avoid accidental 

tripping of the valve, this section of cable run must not be strained 

by normal handling of the loading hose. 

4. Continue clamping cable to hose with ties approximately every 12". 

Allow a minimum of 1 /2" of cable slack between ties. The cable need 

only be clamped to half the length of the hose. 

5. Terminate the cable by securing it with the stainless steel hose 

clamp 12" from the last nylon tie. Before the hose clamp is tightened, 

slip the cable through the clamp and make a loop sleeve. Be sure 

to allow 1 /2" of cable slack before tightening hose clamp. 

6. With the valve latched open, move the hose to simulate the normal 

movement of the hose during usage. The valve should not trip. Also, 

check to see if the stainless steel hose clamp has slipped, and if so, 

re-adjust and tighten. Note: The only time that the cable will trip the 

valve closed is when a truck accidently pulls the hose and causes 

the hose to stretch.

Installation — see Figures 1 & 2 

Install the valve in the vapor return line on the plant side of the bulkhead. 

The valve should be in the fixed piping of the transfer system within 20 

feet (along the pipe lineally) from the nearest end of the hose or the 

swivel type piping to which the hose is attached. If the valve is installed 

more than 5 feet from this hose end connection, an ECII ® 7606A 

Remote Closing Device must be installed within 5 feet of the hose end 

connection. 

To Test For Operation — see Figure 3 

1. Rotate Cam Lever counterclockwise to open valve. The Locking 

Arm Assembly will engage in this position. 

2. Rotate the Latching Arm Assembly clockwise to close valve. 

3. Check Installation: (a) close hose end valve; (b) open ESV (c) 

charge system with LP-Gas and (d) check all connections for 

leakage. 

Important: This ESV has a pressure equalizing feature built into it. It will 

open with nominal manual effort if LP-Gas pressure is on both sides of 

the check. If the ESV is closed with LP-Gas pressure behind the check 

only, the opening effort is greater and the following procedure must be 

used: 

Turn the operating lever slightly. This opens the equalizing valve built into 

the valve check; wait until the LP-Gas pressure has equalized across the 

valve seat and the ESV will open with nominal effort. 

Thermal Fuse Replacement — see Figure 4 

The locking arm which contains the thermal fuse element is an integral 

component of the fuse release assembly 7781A-29. If it is necessary to 

replace the fuse element, then the above assembly must be replaced 

with a factory replacement unit. To remove the fuse release assembly 

from valve, disengage locking arm and remove roll pin (1747-8) from 

stem. Then slide out cam lever (7781A-5) and unscrew locking nut 

(7781A-17) from stem. The topworks unit is now free to remove from 

the valve body. 

Reverse above procedure to install new unit being sure the base plate 

tab is seated in the alignment groove on top of the valve body. If a remote 

closing device is used, see instruction sheet 7608-301.

Cable Attachment — see Figures 1 and 3 

The locking arm assembly is designed to be pulled from either the 

storage tank side or the loading side of the valve. In either case, the line 

of pulling force should be in line with the axis of valve bore. Therefore, 

when attaching a cable from the valve to the end of the transfer hose, 

a guide pulley may be required to obtain in-line axis pulling force. 

The 8-32 threaded holes in the locking arm assembly are used to 

connect a 1 /16" diameter cable. The connection can be made by a loop 

with a sleeve spice (supplied in ECII ® 7609-50 Transfer Cable Kit or 

7608-50 Manual Remote Control Cable Kit). 

An alternate type of connection can be made with an 8-32 x 1 /4" long 

machine screw and washer. Be sure to use 7 x 7 strand, 1 /16" diameter 

cable. 1 x 7 strand cable is too stiff causing difficulty in flexing around 

the screw. It will also be difficult to use in making a loop type connection. 

NOTE: Before making final tension adjustments, latch valve in the open 

position. If the latch closes the valve while adjusting the tension, then the 

cable is too taut. It may take a few times to "tune" the cable tripping 

system. 

Installing Remote Closing Device — see Figure 5 and refer 

to 7606A-301 Instructions 

The remote unit should be mounted in a vertical position. It will function, 

however, in any position as long as the pull on the cable is in line with 

the directional pull on the handle of the device. 

Mount the Manual Remote Closing Device on the plant side in the 

desired location. Splice additional 1 /16" diameter stainless steel aircraft 

cable, 7 x 7 strand (Kit 7608-50) to the rear cable (1) supplied with the 

ESV valve, running the additional length through thin wall conduit to the 

remote closing device. Take up slack at the turnbuckle provided, so that 

cable from the ESV valve to the remote closing device is taut, but not 

strained. Pull handle on remote closing device and check to see valve 

closes. 

CAUTION: If there is excessive tension on the cable it may prevent 

complete engagement of the latching mechanism. As a result, any 

form of vibration or accidental jarring of the valve could cause 

premature closing. 

Transfer Hose Cable Closing Kit — see Figure 1 and refer to 

7609-301 Instructions 

Connect necessary loading hose to system. The forward cable on the 

valve can be extended with a spliced length of cable to the loading hose 

beyond the bulkhead. This cable should be strapped to the loading hose 

at the proper distance from the bulkhead , so that if the vehicle pulls away 

without disconnecting the hose , the slack being taken up by the moving 

vehicle or the stretch in the hose will pull the cable and close the valve. 

Most new hoses will elongate about 70% before separating. 

NOTE: The point closest to the valve at which the cable should be 

clamped to the loading hose must be determined by the unique 

requirements of each installation. Additional clamps should be installed 

at 1 foot intervals with an extra 1 /2" of cable allowed per foot of hose 

length, permitting free movement of the hose without nuisance closing. 

IMPORTANT: The cable-to-hose connection most distant from the 

valve must be securely clamped — Figure 1.

Application 

The RegO ® A7853PA Pneumatic Actuator is designed especially for 

operating RegO ® A7853A 3-Way Valves used in conjunction with 

RegO ® A7883FK and A7884FK Flomatic ® Internal Valves. This 

Pneumatic Actuator provides a simple and convenient means to 

open and close the A7853A 3-Way Valve which controls the differential 

pressure into the Flomatic. This differential pressure opens 

and closes the Flomatic ® Valve. 

The A7853PA is only for use on the RegO ® A7853A 3-Way Valve 

when used in conjunction with RegO Flomatic ® Internal Valves. Do 

not use actuator in other applications. Responsibility for proper 

installation must be assumed and met by the installer. 


The A7853PA Pneumatic Actuator can be pressurized with an 

existing pneumatic system. The actuator is designed to move the 

A7853A 3-Way Valve’s lever to the “Up & Open” position when 

pressure is applied and return it to the “Down & Closed” position 

upon loss of pressure. The A7853PA operates with a minimum 

pressure of 50 psig and a maximum operation pressure of 150 psig. 


for use on A7853A 3-Way Valves 

in Flomatic ® Installations 


1. Before beginning installation of the A7853PA, verify that the 

following requirements are met: 

a. The LP-Gas system is shut down to prevent accidental 

operation of the system and to prevent the escape of LP-Gas 

during the installation. 

b. Installation must only be performed by qualified personnel, 

fully proficient with compressed air systems. 

c. There is sufficient space at the A7853A 3-Way Valve to 

accommodate the pneumatic actuator. Hoses and wires 

must not be jeopardized by the operation of the actuator. 

d. A flat mounting surface exists for mounting the pneumatic 

actuator. This may be part of a truck frame. The back side 

area of this surface must be inspected for any devices which 

could be damaged from drilling during installation. 

e. The A7853A 3-Way Valve must be mounted securely. System 

piping alone is not sufficient to hold the valve securely 

when using the actuator. There are (2) 3 /8" x 16 UNC bosses 

located on the back of this valve for mounting. 

2. Disconnect any devices that are attached to the lever of the 

A7853A 3-way Valve. 

3. If the lever of the A7853A Valve is: 

a. flat with a milled slot in the middle – proceed to Step 6. 

b. round without a milled slot – continue with Step 4. 

CAUTION: Be sure the lever does not flip to the "Up & Open" 

position during this installation. 

4. Carefully remove the roll pin securing the lever to the valve stem. 

Use an appropriately sized punch and hammer if needed.

5. Place the new A7853A-75H lever over the valve’s stem in the 

“Down & Closed” position. Lever must be purchased separately. 

Align the holes of the lever and stem. Insert roll pin and secure. 

6. Mark a Reference Point on the mounting surface. This point must 

be 17 /32" above and 4 3 /32" offset from the hole where the roll pin 

is inserted into the lever and stem. See diagram. 

7. Drill (2) 1 /4" holes in mounting plate. Position holes directly 3 /4" 

above and 3 /4" below the Reference Point. See diagram. 

8. Position the spacers provided between the mounting bracket 

and mounting surface as shown. Secure bracket to the surface 

using the cap screws, washers, lock nuts, and nuts supplied. 

9. Install the pneumatic actuator onto the mounting bracket using 

the bracket lock nut to secure. 

10. Thread the yoke lock nut onto the actuator shaft. 

11. Thread the yoke onto the actuator shaft until the threads of the 

actuator are flush with the inside of the yoke. Secure the yoke's 

position with the yoke lock nut. 

12. Line up the end holes in the yoke with the milled slot in the lever. 

It may be necessary to pull out the spring loaded actuator shaft 

up to 1 /2" to line up the holes with this slot. Install the yoke pin 

through the yoke and lever. Slide the (2) e-rings provided into the 

grooves on the yoke pin to secure the pin in place. 

Caution: Make sure the palm button is fully depressed before 

installing. 

13. Install the push-pull palm switch (available separately) at a 

location convenient for the operator but where it will not be 

subject to accidental operation from being bumped. 

14. Connect a hose from the air source to port # 2 of the palm switch. 

Install a 1/4" NPT "TEE" to port #1 of the palm switch and then 

connect a hose from the "TEE" to the inlet of the pneumatic 

actuator. (The 1/4" NPT "TEE" is to be supplied by the customer 

for installation of the thermal fuse). 

Note: The pneumatic actuating system employed must meet the 

requirements and provisions of NFPA #58, DOT, ANSI, and all 

applicable federal, state, provinicial, and local standards, codes, 

regulations and laws. 

Testing 

Caution: Make sure the propane system is inactivated before 

testing installation. 

Verify that the palm switch is fully depressed and the lever on the 

3-Way Valve is in the “Down and Closed” position. When the palm 

switch is pulled, the actuator should push the lever in to the “Up and 

Open” position. The “Up and Open” position is vertical or slightly 

past vertical. 

Maintenance 

The pneumatic actuator must be inspected for excessive wear at all 

the connection points during the system’s scheduled maintenance. 

Replacement of worn parts is essential to safe operation of the 

LP-Gas delivery system.

WARNING 






























A7883FK & A7884FK 

Flomatic Internal Valves 

For direct pump mounting on trucks, 

transports, and bulk storage in LP-Gas 

and NH3 service. 

Application 

The A7883FK Series Internal Valves are designed primarily for 

LP-Gas and anhydrous ammonia liquid withdrawal on MC331 

bobtail delivery trucks, transports, and large stationary storage 

containers with flanged connections. The valve is fully automatic, 

opening and closing as the pump is turned on or off. 

Fully Automatic 

• Operates on pressure differential from the pump to open and 

close. 

• Automatically closes should downstream line rupture causing 

loss of pump differential pressure required to keep the 

valve open. 

• Eliminates problems of improperly sized excess flow valves 

slugging shut during liquid transfer. 

Faster Unloading 

• Straight through flow design provides minimum pressure 

drop and large flow capacity to the pump, resulting in higher 

flow rates and greater pump efficiency. 

• Unloading is quicker and turn-around faster to provide more 

profitable operation. 

Greater Protection 

• Fully automatic operation virtually eliminates operator errors 

such as forgetting to close the valve after product transfer. 

• Fully internal design reduces possibility of spillage that may 

result from a collision. 

• Built-in visual indicator lets the operator know whether the 

valve seat is in the open or closed position. 

• Never a cable problem. The valves must NEVER be held 

open by wire or any other means as the valve will not close 

as expected when the pump is shut off. 

Less Maintenance 

• Easily replaceable, high efficiency external filter removes 

contaminants as small as 20 microns. 

• No need to check or replace air lines, cables, or cable 

connections. 

Economical 

• Completely equipped with mounting bolts, flange gaskets, 

quick acting valve, and filter -- all in one purchase price. 

• No need to purchase additional mounting equipment or 

actuating accessories. 

• Specify the Flomatic ® on your next new tank body or when 

your tank is rebuilt.

product transfer. A line break downstream of the pump may fail 

to actuate the excess flow valve as the pump may limit flow. If 

a break occurs in the system, or the excess flow closes, 



How the Valve Works: 

1. Normally Closed 

While the valve is closed, liquid flows into the INLET PORTS, 

and through a channel in the PISTON into area A. It also flows 

down through the PRIMING CHANNEL in the valve body, into 

area B beneath the valve seat -- and into area C to prime the 

PUMP. 

Installation, disassembly, repair and maintenance must be 









be kept far enough from any open flame or other source of 

ignition to prevent fire or explosion! LP-Gas is heavier than air 

and may not disperse or evaporate rapidly if released in still air. 

2. Pump on — Valve Opening 

When the pump is started, differential pressure transmits through 

the 1 /4” piping into chamber D, lifting the PILOT STEM. This 

opens the seat between the stem and piston at E. Pump suction 

then evacuates the tank pressure in area A, which becomes 

equal to the pump suction pressure.

3. Pump On — Valve Open 

Tank pressure exerted on the X-RING SEAL forces the PISTON 

up to open the valve. This rotates the INDICATOR SLOT to its 

vertical (valve open) position. The pump differential pressure in 

area D holds the PILOT STEM and PISTON open. Approximately 

18 psig pump differential pressure is required to open the 

valve and approximately 8 psig differential pressure will hold the 

valve open. 

4. Pump Off — Valve Closes 

With the pump shut off, the pressure in area D which holds the 

valve open, bleeds out through the # 60 DRILL ORIFICE. This 

loss of pressure permits the SPRING to push the PILOT STEM 

down and re-seat at point E. Since pressures are equal above 

and below the PISTON, with no sustaining pressure in area D, 

the SPRING forces the valve closed. The INDICATOR SLOT 

rotates to the horizontal (valve closed) position.

Installation 

The 8542 Series is designed especially for use as a primary relief device 

on smaller stationary storage containers up to 1200 gallons water 

capacity with 2" NPT threaded couplings. These manifolds allow 

servicing or replacement of either of the two relief valves without 

evacuating the container or loss of service. The operating lever 

selectively closes off the entrance port to the relief valve being removed 

while the remaining valve provides protection for the container and its 

contents. The rating of each manifold is based on actual flow through 

the manifold and a single pressure relief valve, taking friction loss into 

account. It is not merely the rating of the relief valve alone. 

If the DuoPort Manifold is to be used with a vent stack, the following 

installation procedures should be observed: 

1. Be certain that an ECII ® 3135-10 pipe-away adapter is threaded 

into the outlet of each safety relief valve. In addition to providing a 

2" NPT female connection for the installation of 2" pipe, this adapter 

has an externally machined weakness groove to facilitate breakage 

at this point, leaving the valve itself fully operative in case undue 

stresses are applied to the vent piping. 

2. Limit the height of the vent stack to a minimum. Be sure to include 

the approximate overall height of the DuoPort (11 9 /16") in 

determining the overall height of the vent required above the top of 

the container. 

3. Secure the two vent stacks firmly to each other midway or at the top 

to break the wind velocity between the stacks and to reduce the 

tendency to vibrate or oscillate. This may be accomplished by 

inserting a wooden block between the stacks and clamping them 

together at this point.

Installation, Operation and Service 

Instructions 

Operation 

In normal operation, the handle is kept at the center stop. In this 

position, both relief valves are open to the container vapor space. This 

provides extra relief capacity by permitting both valves to function 

simultaneously if necessary. 

To remove a safety relief valve for retesting or replacement: 

1. Pull out the locking latch to release the handle. See Figure 1. 

2. Rotate the handle upward to position beneath the valve to be 

removed. See Figures 1 and 3. 

3. Release the locking latch when the handle clears the ledge marking 

the off position. The spring loaded latch automatically retains the 

handle in this position.

4. Do not attempt to remove the safety relief valve until the vapor 

trapped between the valve seat disc and clapper disc is exhausted. 

5. To exhaust the trapped vapor, turn the appropriate bleeder valve 

clockwise until it is firmly seated in the closed position. The vapor 

will then vent. If this discharge continues for more than a few 

seconds, either the handle is not firmly locked in the off position or 

the bleeder valve is not completely shut-off. See Figure 2. 

6. Once the vapor discharge stops, do not attempt to move the handle. 

7. The 2 11 /16" wrench flats on the safety relief valve facilitate removal 

after the discharge stops. The tank vapor pressure maintains a 

leak-tight seal between the clapper disc and seal ring. 

8. If an extra safety relief valve is not immediately at hand to replace 

the one that was removed, the open port must be sealed with the 

rubber stopper to prevent the entrance of moisture and contaminants. 

Do not use a pipe plug or otherwise make a pressure-tight 

seal. This may allow internal pressure to equalize, and permit 

turning the handle to close off the other safety relief valve, leaving 

the tank unprotected. Do not attempt to move the handle or bleeder 

valves while any port is without a safety relief valve. 

Valve Replacement 

NOTE: Use only ECII ® 3135 Safety Relief Valves in ECII ® 8542 

DuoPort Manifolds. These valves have been specially machined for 

this service. 

Repair must be performed in a clean area. Hands, clothing, tools and 



1. Apply a small amount of a suitable pipe joint compound to the male 

threads of safety relief valve. Do not apply compound to DuoPort 

threads. 

2. Screw in the replacement safety relief valve, using sufficient torque 

to produce a leak-tight seal. 

3. Turn the bleeder valve counterclockwise until it back-seats firmly. 

This permits pressure equalization between the tank and the space 

below the safety relief valve. 

4. Use a high quality leak detection solution to check the seal on the 

replaced safety relief valve to assure a leak tight seal. 

5. The handle should now be returned to the center stop and locked 

in place so that the clapper is not under either safety relief valve.

If the DuoPort Manifold is to be used with a vent stack, the following 

installation procedures should be observed: 

1. Be certain that an ECII ® AA3135-10 pipe-away adapter is threaded 

into the outlet of each safety relief valve. In addition to providing a 

2" NPT female connection for the installation of 2" pipe, this adapter 

has an externally machined weakness groove to facilitate breakage 

at this point, leaving the valve itself fully operative in case undue 

stresses are applied to the vent piping. 

2. Limit the height of the vent stack to a minimum. Be sure to include 

AA8542 Series DuoPort 

Safety Relief Valve Manifold 

Installation, Operation and Service 

Instructions 

the approximate overall height of the DuoPort (11 11 /16") in determining 

the overall height of the vent required above the top of the 

container. 

3. Secure the two vent stacks firmly to each other midway or at the top 

to break the wind velocity between the stacks and to reduce the 

tendency to vibrate or oscillate. This may be accomplished by 

inserting a wooden block between the stacks and clamping them 

together at this point. 

Operation 

In normal operation, the Handle is kept at the Center Stop. In this 

position, both relief valves are open to the container vapor space, 

providing extra relief capacity by permitting both valves to function 

simultaneously if necessary. 

To remove a safety relief valve for retesting or replacement: 

1. Pull out the Locking Latch to release the Handle. 

2. Rotate the Handle upward to position beneath the valve to be 

removed. 

3. Release the Locking Latch when the Handle clears the ledge 

marking the Off position. The spring loaded latch automatically 

retains the Handle in this position. 

4. Do not attempt to remove the safety relief valve until the vapor 

trapped between the valve seat disc and clapper disc is exhausted. 

5. To exhaust this trapped vapor, turn the appropriate Bleeder Valve 

clockwise until it is firmly seated. The vapor will then vent. If this 

discharge continues for more than a few seconds, either the Handle 

is not firmly locked in the Off position or the Bleeder Valve is not 

completely shut-off. 

6. Once the vapor discharge stops, do not attempt to move the Handle.

7. The 2 11 /16" wrench flats on the safety relief valve facilitate removal 

after the discharge stops. Tank vapor pressure maintains a leaktight 

seal between the Clapper Disc and Seal Ring. 

8. If an extra safety relief valve is not immediately at hand to replace 

the one that was removed, the open port must be sealed with the 

Rubber Stopper to prevent the entrance of moisture and contaminants. 

Do not use a pipe plug or otherwise make a pressure-tight 

seal. This may allow internal pressure to equalize, and permit 

turning the Handle to close off the other safety relief valve, leaving 

the tank unprotected. Do not attempt to move the handle or 

bleeder valves while any port is without a safety relief valve. 

Valve Replacement 

NOTE: Use only ECII ® AA3135 Safety Relief Valves in ECII ® AA8542 

DuoPort Manifolds. These valves have been specially machined for 

this service. 

Repair must be performed in a clean area. Hands, clothing, tools and 



1. Apply a small amount of 5555PM leaded pipe compound, or a 

similar non-hardening compound, to the male threads of safety 

relief valve. Do not apply compound to DuoPort threads. 

2. Screw in the replacement safety relief valve, using sufficient torque 

to produce a leak-tight seal. 

3. Turn the Bleeder Valve counterclockwise until it seats firmly. This 

permits pressure equalization between the tank and the space 

below the safety relief valve. 

4. Check the seal on the replaced safety relief valve to assure there is 

a leak tight seal. Use a high quality leak detection solutuion. 

5. The Handle should now be returned to the Center Stop and locked 

in place so that the Clapper is not under either safety relief valve.

Foreword 

MultiPort TM Pressure Relief Valve Manifold Assemblies are designed for 

continuous, uninterrupted service on pressurized storage containers 

with flanged openings. These manifolds permit servicing or replacement 

of any one of the pressure relief valves while the container is under 

pressure. The container does not need to be evacuated. A handwheel on 

the manifold is designed to selectively close off the entrance port to the 

relief valve being removed without interrupting the operation of the other 

relief valves – saving time and money when relief valve replacement 

becomes necessary. 

The pressure relief valves used on these manifolds are all of the “popaction” 

design. The design permits the relief valve to open slightly to 

relieve moderately excessive pressures, keeping fluid waste to a minimum. 

When pressures increase beyond a predetermined point, the valve 

is designed to “pop” open its full discharge capacity to relieve pressure 

quickly. 

RegO ® 8560 & 8570 Series MultiPort TM Pressure Relief Valve Manifolds 

are compatible with LP-Gas and anhydrous ammonia ( NH3) as follows: 

A prefix before number compatible with both LP-Gas and NH3. 

AA prefix before number compatible with NH3 only 

MultiPort TM Installation 

MultiPort TM Container Connections – See Figure 1 

• A8563G and A8564G manifolds have a flat faced flange with a 

6 5 /8" bolt circle diameter. This is a standard 3" flange but the port 

diameter is 4". The mating flange on the container must also have 

a 4" port diameter. The proper gasket, part # 7564-48, is 

furnished with each manifold. 

• A8573G, AA8573G, and A8574G manifolds have a 1 /16" raised 

face flange with a 7 7 /8" bolt circle diameter. This is a standard 4" 

flange. The proper gasket, part # 7565-48, is furnished with each 

manifold. 

MultiPort TM manifolds are usually installed on either a man hole cover 

plate or a welding neck flange. It should be mounted in a position 

where the handwheel is easy to read and operate. Bolt studs and 

nuts should be used to install the manifold. These bolt studs and 

nuts should be 3 /4" - 10 alloy steel 193-66 grade B-7. 

• For manhole cover plates – use (8) 3 1 /2" long bolt studs – available 

as kit # 7560-56, if not available locally. See Figure 2. 

• For welding neck flanges – use (8) 4 1 /4" long bold studs – available 

as kit # 7560-55, if not available locally. See Figure 3. 

Tighten the bolt studs and nuts gradually in an alternate and 

MultiPort TM Pressure Relief 



opposite sequence around the diameter. Follow the sequence shown 

in Figure 4. 

For normal operation with all relief valves in place, the bleeder valves 

located below each manifold port should be turned counterclockwise 

until fully backseated. Keep the bleeder valves in this position 

during normal operation. See Figure 5. 

After the container is pressurized, check the seal of the flange makeup 

by applying a non-corrosive leak detection solution. If bubbles 

appear, tighten the bolts until the flange seals. If this does not work, 

the flanged surface needs to be checked. 

There is an arrow directly below the handwheel on the manifold body. 

For normal operation with all relief valves in place, the handwheel 

should be turned so the arrow on the body is midway between any 

two (2) adjacent numbers on the handwheel. In this position, all four 

relief valves are available to provide extra relief capacity if necessary.

Extra Tank Openings 

In many cases, the installation of a MultiPort TM results in one or more 

empty flanged openings in the container which were formerly 

occupied by individual flanged relief valves. These extra openings 

can either be sealed off or used for extra withdrawal capabilities. 

Openings can be sealed with properly sized and rated blind flanges. 

Extra threaded openings can be provided by using a screwed 

reducing flange with the required thread size.

Relief Valve Removal 

NOTE: Before beginning relief valve removal or inspection, be sure 

protective eye wear and gloves are worn. Do not look directly into 

the relief valves at any time because they may discharge and cause 

bodily injury. No more than one relief valve may be removed from the 

manifold at any one time. 

The relief valve ports are numbered clockwise from the positioning 

handwheel. The one at the left of the handwheel is number one (1) 

and the one at the right is number four (4). Note the number of the 

manifold body port into which the relief valve to be removed is 

threaded. Turn the positioning handwheel until the number on the 

handwheel which corresponds to the number of the relief valve to 

be removed is in line with the arrow on the manifold body directly 

below the handwheel. See Figure 6. This procedure should position 

the manifold's shut-off disc under the desired port. Proper location 

and positioning of the shut-off disc can be checked using the 

bleeder valve directly below the port where the relief valve is to be 

removed – as instructed below. 

Turn the handwheel of the bleeder valve in a clockwise direction 

until it seats. See Figures 6 and 7. This procedure should allow 

propane vapor to bleed from the hole in the bleeder valve body and 

release the pressure between the manifold shut off-disc and the 

relief valve. 

After the discharge stops, the relief valve is ready to be removed. If 

the vapor continues to discharge for more than one minute, the 

manifold shut-off disc is either not fully seated or not properly 

positioned. The bleeder valve handwheel must then be back seated 

by turning in a counterclockwise direction to equalize the pressure. 

This should allow the free turning of the positioning handwheel for 

repositioning. When the manifold shut-off disc is properly positioned, 

the bleeding operation must then be repeated as earlier 

described. 

WARNING: Never attempt to move the manifold shut-off disc 

via the positioning hand wheel after pressure has been bled off 

or the relief valve has been removed. 

After the manifold shut-off disc has been properly positioned and 

the pressure beneath the relief valve has been bled out, the weep 

hole deflector must be removed from the relief valve. See Figure 8. 

Remove the weep hole deflector with an appropriate wrench. This 

provides clearance for gripping and turning the relief valve with a 

wrench. 

The relief valve may now be removed with an open end wrench, 

monkey wrench, pipe wrench or chain wrench applied to the hex 

section of the relief valve. 

If the relief valve cannot be replaced immediately, the rubber 

stopper must be placed in open port to prevent the entrance of 

foreign material. See Figure 9. Give the stopper a half turn to engage 

a few threads. Do not use a pipe plug or otherwise make a pressure 

tight seal. A seal would permit turning the positioning handwheel so 

another relief valve could be closed off. This would leave the 

container with inadequate protection and is not permissible. 

In some cases, it may be necessary to remove the positioning 

handwheel to facilitate removal of relief valves one and four. If this 

is done, carefully note the position of the handwheel and replace it 

in exactly the same position. This can be verified by matching the 

number of the closed port, the number on the handwheel and the 

arrow stamped on the manifold body pad directly below the 

handwheel.

Using the same wrench on the hex section of the relief valve, 

screw the replacement relief valve into the open port. Tighten 

down with sufficient torque to provide a leak-tight seal. 

Apply pipe compound to the male threads of the weep hole 

deflector and install it into the outermost tapped opening of the 

relief valve. Be sure the remaining two openings are plugged. 

The deflector must be installed so that the large angle bore 

points up. Turn the small handwheel of the bleeder valve located 

below the replaced relief valve counterclockwise until it is fully 

backseated. This procedure will allow pressure to equalize 

between the manifold shut-off disc and the relief valve. The 

positioning handwheel should now be free to turn. 

During normal use, with all relief valves properly in place, it is 

recommended that the handwheel be turned so that the manifold 

shut-off disc is positioned between any two relief valves. 

This is accomplished by positioning the handwheel so the arrow 

on the manifold body points between any two numbers on the 

handwheel. This will provide extra relief capacity so that all of the 

relief valves can function if necessary. 

Check the connection of the replaced relief valve and manifold 

with a high quality leak detecting solution. If bubbles appear, 

there is a leak. The connection must be leak-tight.
