New 3" and 4" pipe-size thermoplastic check valves from Plast-O-Matic are normally-closed and require no reverse flow to seal bubble tight. The design features no wetted metals, and the valves are ideal for use with highly-aggressive chemicals in a variety of wastewater treatment applications. Closure is provided by an isolated, Teflon- encapsulated spring. Leak-free sealing protects against the potential hazards created by reverse-flow corrosive liquids such as acids, caustics and chlorine solutions. The valves offer positive repetitive sealing where the poppet automatically positions itself against seat in the identical location each time for long cycle life dependability.
