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 check or swing check valves do not.
