All Triangle Pump valve units are designed for easy installation with minimum disassembly. When inspection shows that wear has occurred, however, proper maintenance such as replacing the valve disc, spring, and sleeve, or torqueing studs, bolts, and locknuts may be required. We also recommend re-facing or reinstalling the seat to eliminate any ridges at the inner or outer edges.
Valve Puller Components
Detailed instructions and installation tools are available with each pump valve order. Triangle Pump valve pullers include the following components:
- Puller Claw – 1” Internal Thread to be threaded onto the All Thread Rod (2) as far as the Rod will thread into the Claw. The Claw Nut (3) should then be “snugged” up to the Claw. This will prevent any wobble in the Claw to Rod connection.
- All Thread Rod – 1” Diameter.
- Claw Nut – Should be “snugged” up to the Claw.
- Strong Back Bottom Nut – This is used primarily to keep the Strong Back (5) from sliding down the Rod while preparing to pull the valve. This Nut is not necessary to pull the valve.
- Strong Back – This is placed across the valve port of the pump.
- Strong Back Top Nut – This Nut is used to lock the Strong Back firmly in place on the pump. It is extremely important that the Nut be very tight on the Strong Back. If the valve does not loosen on the first bump, tighten the Top Nut again. A loose Top Nut can cause the prongs of the Claw to stretch out or break.
- Hammer – This provides the impact to pull the valve.
- Hammer Nut – The Hammer strikes the Hammer Nut in a quick upward motion.
- Hammer Nut Locknut – This Nut serves to keep the Hammer Nut from moving during impact. It should be tightened up against the Hammer Nut.
Removing A Valve With The Valve Puller
To safely remove a pump valve, follow these steps:
- Follow the Claw to Rod assembly instructions as outlined in number one of the parts list. Make sure that the All Thread Rod (2) is threaded into the Claw (1) as far as possible. Make sure that the Claw Nut (3) is tight against the Claw.
- Fit the Claw (1) through the webs of the valve seat. Turn the Claw to the right until the Claw prongs meet the webs of the seat. Pull up on the Rod until the ends of the Claw are hooked around the webs. Tighten the Top Strong Back Nut (6) until it will no longer tighten.
- The Strong Back (5) should be resting in place on the valve port of the pump. Tighten the Strong Back Nut (6) until it will no longer move (this is very important). If this Nut is not properly tightened, the Claw will stretch or break.
- The Hammer (7) should now be resting on the Top Nut of the Strong Back. Make sure that the Hammer Nut (8) is located no less than six inches above the Hammer. Tighten the Locknut (9) in place.
- Grasp the Hammer by each handle making sure to pull straight up. Pull upward on the Hammer in a quick, forceful motion. At this point, try to tighten the Top Strong Back Nut once again.
- Continue to Strike the Hammer against the Nut until the valve loosens.
- Repeat these steps on all of the valves.
