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 Swing Check valves offer up to twice the temperature/pressure rating of other plastic swing check valves and can often replace metal valves in many applications. Available in PVC, CPVC, or GFPP with either FPM or EPDM seals. These valves can be installed horizontally or vertically, and have a counterweight or spring available for assisted closing.
