Description
Dual-plate wafer-type check valve with two spring-loaded plates that open under forward flow pressure and close automatically when flow stops or reverses. The wafer-style body installs between standard flanges. Available in cast iron, ductile iron, carbon steel, and stainless steel body construction.
Selection notes
This check valve is a wafer type and dual plate pattern, supplied for wafer installation.
Sizes run DN50 to DN800, in PN10, PN16, ANSI Class 150, JIS 10K.
The body is offered in Cast Iron, Ductile Iron, Carbon Steel and Stainless Steel, so the grade can be matched to the service rather than the other way round.
Seat and trim options are NBR, EPDM, FKM and Neoprene. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include fresh water, sewage, sea water, air, vapour and oils.
It is catalogued for Water & Wastewater, HVAC and Industrial Process.
Working temperature is max 150°C.
Built to API 594, DIN 3202, ISO 5752, API 598 and ISO 5211.
