AAP Single Disc Wafer Check Valve, 2"

This AAP single disc wafer check valve has a cast iron body, a 316 stainless steel disc and spring, an EPDM seat, NBR flange gaskets and a 2Cr13 axle. It is supplied in 11 sizes from 2" (50mm) to 16" (400mm). A single disc wafer check valve has one disc on an axle and a spring, and it fits between two pipe flanges. Forward flow pushes the disc open and the spring closes it as flow stops or reverses.

The maximum working temperature is 120°C and the cold working pressure is 1,000 kPa (10 bar), with flanges to AS 2129 Table E. EPDM suits water but is not normally used with petroleum oils.
