Series 2200/2220 Control Valve - Alberta Oil Tool

Operation and Maintenance 

SCOPE OF MANUAL 

This instruction manual includes installation and 

maintenance information for the 1.00" and 2.00" Series 

2200/2220 Control Valves. Refer to separate manuals for 

instruction covering controllers, positioners, etc. 

DESCRIPTION 

The Series 2200/2220 valve design has a close coupled or 

yoke mounted pneumatic diaphragm actuator, hammer nut 

closure, and unbalanced valve plug. 

VALVE INSTALLATION 

1. Before installing the valve, inspect for shipping damage 

and for any foreign material that may have collected 

during crating and shipping. Remove plastic plugs for 

flange protectors from body. 

2. Blow out pipelines to remove pipe scale, chips, welding 

slag, and other foreign materials. 

3. Install valve in pipeline, with direction of flow through 

body determined as follows: 

3.a. Directed over the seat ( 

opening trim, 

3.b. Directed under the seat ( 

modified percent trim. 

)for quick 

) for 

4. Install valve using good piping practice, with actuator 

vertical above body. Flanged bodies will require a 

suitable gasket between the body and pipeline flanges. 

5. Working pressure of valve body is not necessarily the 

shut-off pressure of the valve actuator. Consult the 

shut-off tables or factory. 

6. The series 2200/2220 bodies are rated for ANSI classes 

150, 300, 600, 900, and 1500. Do not install the valve 

in a system where the working pressures exceed those 

specified in the standards. 

7. Connect instrument air to actuator. 

8. Actuators with adjustable spring can be adjusted to 

increase or decrease shut-off capability. Turn clockwise 

to increase pre-load, turn counterclockwise to decrease 

pre-load. 

MAINTENANCE 

Series 2200/2220 Control Valve 

CAUTION 

Before attempting any repairs, isolate the control valve from 

the system and make sure that all pressure is released from 

the valve body. 

A. VALVE DISASSEMBLY INSTRUCTION 

1. When the actuator is to remain connected: 

1.1. For reverse (Spring Closing) actuators, remove 

all spring compression by unscrewing adjusting 

screw (item 20). 

1.2. Disconnect air supply line from actuator. 

1.3. Unscrew hammer nut (item 5) from body (item

1.4. Lift entire topworks (actuator assembly with 

valve stem (item 11) and plug attached) from 

valve body (item 1) and place on a flat work 

surface. 

CAUTION 

Be careful with plug and extended stem, protecting the stem 

from being bent. 

1.5. Remove plug (item 2) using 1/8 inch drift pin or 

punch, drive roll pin (item 15) from plug (item

CAUTION 

Protect stem from bending by using a solid block as back-up 

while hammering the roll pin from plug. 

1.6. Pull seat/cage (item 3) from body (item 1). (It 

may be necessary to use a hook, hooked in the 

cage flow openings. 

1.7. Replace seat/cage and reassemble valve by 

reversing the procedure of steps 1 through 6. 

2. When actuator is to be disconnected and taken 

off the body: 

2.1. See "Actuator Disassembly" 

2.2. Unscrew hammer nut (item 5) and lift off over 

bonnet (item 10). 

2.3. Remove bonnet (item 10) from body (item 1) 

along with valve plug (item 2) and stem (item 

11). 

2.4. Remove valve plug (item 2) from stem (item 

11).Using 1/8 inch drift pin or punch, drive roll 

pin (item 15) from plug (item 2).

is accomplished by reversing the 

procedure of steps 1 though 6.

(item 11). 

1.5. Remove lock washer (item 32), spring retainer 

(item 24), bearing washer (item 26), diaphragm 

plate (item 21) and diaphragm (item 17). 

1.6. Unscrew lower housing (item 16) from yoke 

(item 25) or bonnet (item 10). 

1.7. Loosen jam nut (item 38) that secures valve stem 

(item 11) to actuator stem (item 26) and unscrew 

the stems.

C. ACTUATOR ASSEMBLY 

1. Reverse Actuator 

1.1. Reverse the procedure of "Actuator Disassembly" 

- Reverse Actuator. 

2. Direct Actuator 

2.1. Reverse the procedure of "Actuator 

Disassembly", - Direct Actuator. 

D. PREVENTIVE MAINTENANCE 

1. Seat 

1.1. Check every six (6) months if in normal service, 

i.e., no sand or abrasives and low pressure drop. 

If in severe service, i.e. high pressure drop and 

sanding condition, check every sixty (60) days. 

2. Inner Valve 

2.1. Same as above. 

3. Bonnet 

3.1. Check packing every year. 

4. Actuator 

4.1. Check diaphragm and o-rings once a year. 

5. General Maintenance 

5.1. When disassembling any portion of valve, always 

check o-rings for damage or wear before re - 

assembly. 

6. Body 

6.1. Under normal conditions, body should last years. 

However, under severe conditions, i.e. corrosion, 

sand and high pressure drop, valve life could be 

numbered in days only. Inspect body every time 

actuator is removed. 





TROUBLE DIAGNOSIS 

WARNING SIGNAL IMMEDIATE CAUSE CORRECTIVE ACTION 

Valve leaks when in the 

closed position. 

Diaphragm housing leaks air 

from breather plug. 

Valve leaks. Flow under 

plug. Valve normally closed. 

Seat and plug O.K., nothing 

under plug. 

Valve will not open. Flow 

over plug. Normally closed 

valve. 

Something under plug or valve 

plug and seat are worn. 

Worn out diaphragm or 

diaphragm plates have worked 

loose and need tightening. 

Pressure drop across valve too 

great. 

Pressure drop across valve 

seat too great. 

Remove spring tension from valve if a spring closing valve. 

Remove valve top from body by turning hammer nut. By visual 

inspection you can see whether plug and seat are worn. Plug is 

usually the first to be replaced. 

Remove pressure form diaphragm housing and disassemble top. 

Replace diaphragm and o-ring. If nuts that hold diaphragm 

plates are loose, retighten. 

If spring is compressed all the way, then the actuator is too 

small or pressure drop across valve plug is too high. Check 

valve pressure drop table for limits on pressure drop and/or 

consult your Norriseal representative. 

Reduce spring tension. If this will not let valve open, then the 

actuator is too small or pressure drop across valve plug is too 

high. Consult pressure drop table and/or your Norriseal 

representative. 

CAUTION 

Valve globe body has this symbol ( ) cast on one side. Flowing ( ) indicates flow under plug. Flowing 

( ) indicates flow over plug. Flow under seat is for throttle service. Flow over plug can be used for on-off 

service. Flow under seat requires adjustment of the spring to be sufficient to keep plug on seat for tight shut off. 

Flow over seat requires sufficient air supply to raise plug from seat to open valve. 

CAUTION 

When flowing over plug and high pressure service is involved, slapping of plug on seat (Bath tub stopper theory) can occur and 

this will shorten the plug, seat/cage life. 

Reverse - normally closed valve: After applying spring compression to the actuator spring apply air to actuator and stroke valve 

to make sure of valve's travel. 

Direct - normally open valve: Air supply to actuator must be sufficient to hold plug on seat when flow is under plug. Flow over 

seat requires enough pre-load on spring to offset pressure over plug to pull plug off seat. Again you must have sufficient 

air pressure to force the plug into the seat. 

The 1" and 2" globe body has one inlet and one outlet port. The 1" "T" body has three ports, one inlet and one outlet with a pipe 

plug in the third port. Valve can be used for globe or angle flow by moving pipe plug to suit user. If customer moves pipe plug to 

another port after receiving from factory, customer should re-test valve body.
