Plast-O-Matic PVC Self-Closing Check Valves

 

Plast-O-Matic normally closed check valves provide leak-free sealing in any position. Unlike standard ball check valves, they require no backpressure for a positive seal in the closed position. Valves open with 1.0 to 1.5 psi of inlet pressure. Working pressure at 110°F is 150 psi for sizes 1/2", 3/4" and 1"

Valve sizes 1/2", 3/4" and 1" have a flexible diaphragm seal that automatically positions itself against the seat in the identical location in the closed position.

Valve sizes 1-1/2", 2" and 3" have a spring loaded poppet that automatically positions itself when closing for precise seating. The spring is PFA (comparable to Tefl on®) encapsulated stainless steel for absolute chemical isolation. Both types feature a union nut assembly to simplify inspection/removal with minimum piping breakdown.

We offer Plast-O-Matic PVC check valves with your choice of EPDM or FKM seals. FKM (comparable to Viton®) is recommended for use with chlorine solutions, whereas EPDM is preferred for use with sodium hydroxide (caustic soda). For all other chemicals, always refer to chemical compatibility guides. Plast-O-Matic also offers self-closing check valves in PVDF, CPVC and GPP glass filled polypropylene.
