Hayward Thermoplastic Check Valves prevent reversal of flow in piping systems. Hayward Check Valves are ideal where back flow could potentially cause damage to pumps, filters, or process equipment. True union ball check, y-checks, spring-return y-checks, swing and wafer checks are available.
Hayward Thermoplastic True Union Ball Valves also make maintenance easier. Just unscrew the two assembly nuts and lift the valve out of the line for service. Reversible seats only need to be removed, turned over and reinstalled to put a valve back on line. Double o-ring stem seals, easily actuated and many available options make these valves the right choice.
Hayward True Union Ball Check Valves are offered in PVC, CPVC, and PP. O-rings and seats are FPM or EPDM. 1/4 inch and 3/8 inch sizes are PVC only and are trim check design. They have socket or threaded end connections. Others up to 2 inch sizes have socket and threaded end connections. All valves are assembled with silicone free lubricant.
