Hayward Thermoplastic Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters, or process equipment. True union ball check, y-checks, spring-return y-checks, swing and wafer checks available.
NSF/ANSI 61 Listed, Offered in PVC, CPVC and PP. O-rings are FPM or EPDM, and square cut seats are PTFE. All sizes rated to 150 PSI. Sizes up to 2 in. include socket and threaded end connections. Foot valves and smaller trim check design available, consult factory.
Offered in PVC and CPVC with either FPM or EPDM seat and seals. Available with true union end connections as well as spring-return option. Options also include drilled cap for easy drainage. All sizes rated to 150 PSI.
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.
The new patent-pending WCV Series Full Pattern Wafer Check Valve features a
robust thermoplastic construction with industry leading flow rates, and eliminates the
need for spacers or specialty flanges.
Made from thermoplastic materials, the WCV Series has a lighter weight than a metal
equivalent and excellent corrosion resistance. The unique disc seat design allows for
high flow rates and excellent sealing properties. No exposed fasteners or clips in the
media to retain the disc which can break off in the line.
Designed also for global use, the WCV Series fits ANSI and DIN/EN flange patterns. It also
provides a pressure rating of 150 PSI at 70°F Non-Shock
across all sizes where most other plastic wafer
