WARNING: Installation, disassembly, repair and maintenance must be performed only by qualified personnel. Remove all pressure from system before removing hose-end valve, then release lever lock and lift lever to vertical (valve open) position. Remove entire valve from line before performing repairs. Installation, usage and maintenance of this product must be in compliance with all Engineered Control 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 on a periodic basis is essential. 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! NH 3 and LP-Gas must be released outdoors in air currents that will insure 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. Disassembly and Repair Procedure CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS, INCLUD- ING THE NOTICE AND WARNINGS ON THE BACK OF THIS SHEET, BEFORE BEGINNING ANY DISASSEMBLY OR REPAIRS. NOTE: Before repairing valve, thoroughly examine valve lever and all associated parts for excessive wear. Check valve handle for proper functioning, and ACME threads for excessive wear and damage. Check surface of filler connector that seats on filler valve gasket when the valve is used, and make sure it has a smooth surface. 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 matter to prevent contamination of component parts and valves. Disassembly 1. EVACUATE ALL GAS FROM THE SYSTEM BEFORE ANY DISAS- SEMBLY OR REPAIR. Release lever lock and lift lever to vertical (valve open) position. 2. Remove entire valve from line. Clamp the valve body in a vise by the hex end section of the body inlet. 3. With valve lever in the open position, remove entire bonnet assembly by turning clockwise (left-hand threads), using a 11 11 /16" wrench. 4. Remove body gasket and discard. 5. Clean cement residue from body threads using a wire brush. Thoroughly clean all parts of body assembly. Set valve body aside for later reassembly. 6. Clamp the hex section of bonnet in vise. 7. While holding the top of seat disc retainer on flats with a wrench, use another wrench to remove the seat disc retaining nut. 8. Remove and save lower washer, take out and discard seat disc. 9. Immerse new seat disc in water immediately prior to assembly. 10. Install new seat disc by pressing into recess of seat disc retainer. 11. Apply two 1 /8" strips of Locktite across threads on opposite sides of seat disc retainer. CAUTION: Do not allow Loctite to contact seat disc. 12. Place lower washer on seat disc retainer and thread on disc retaining nut. After tightening firmly with a wrench, stake nut in two places at retainer thread to prevent loosening (see figure 2). 13. Return lever to horizontal (valve closed) position. 14. Knock out groove pin with a 1 /4" drift pin. 15. Remove lever. Discard bonnet washer. 16. Pull stem assembly with lower spring out from bottom of bonnet, and keep together. Carefully inspect stem for scoring and scratches in the stem seal area. Deep grooves or scars are cause for replacement of stem and spring.
17. With a suitable wrench, turn seal housing counterclockwise and carefully remove from bonnet. 18. Remove upper washer, jam ring, both pressure seal rings and O-ring from seal housing and discard. 19. Remove and discard seal housing gasket from bonnet. Save upper spring for reassembly. Reassembly 1. Install new seal housing gasket, old upper spring, new upper washer and new jam ring into bonnet. 2. Lubricate and install new O-ring into groove of seal housing (lubricant 5555GS-3, not included). 3. Apply thin film of lubricant to new pressure seal rings and carefully insert one at a time into the full depth of seal housing. 4. Apply 1 /8" strips of Loctite across threads in three places equally spaced around seal housing. CAUTION: Do not allow Loctite to contact gasket. Use sparingly. 5. Place seal housing into bonnet and thread clockwise. Tighten to 500- 600 in/lbs torque. Remove bonnet from vise. 6. Place hex end section of valve body back in vise with bonnet connection up. 7. Apply lubricant liberally to surface of stem and insert stem into body placing seat disc on body seat. Place lower spring over stem onto seat disc retainer. 8. Apply 1 /8" strips of Loctite in three places equally spaced around bonnet across threads. Use sparingly. 9. Install new body gasket into body. NOTE: Push bonnet over the stem making sure a constant force is applied in order to engage the bonnet threads into the body threads. 10. Thread bonnet into body counterclockwise. Tighten to 1000 in/lbs torque with a suitable wrench. 11. Install new bonnet washer. 12. Place lever assembly on stem in horizontal (valve closed) position. 13. Align holes in lever and stem. Install new groove pin and tap in with small hammer until flush with lever. 14. Rotate lever in complete circle to check freedom from binding. 15. Depress lock lever while lifting and release while lowering valve lever to make sure locking leg falls easily over edge of bonnet. Lock lever must not contact flat surface above hex section of bonnet. 16. If necessary, disassemble to free binding parts for proper lock lever operation. 17. Replace valve in line and pressurize while in closed (lever horizontal) position. Check for proper operation and check all seal points for leaks by applying a high quality leak detection solution.
