AAP Ball Check Valve, 2-1/2"

This AAP resilient seat flanged ball check valve has a ductile iron body and cover, an EPDM encapsulated ball and flanges to AS 2129 Table E. It is supplied in 6 sizes from 2" (50mm) to 10" (250mm).

A ball check valve is used where full, uninterrupted flow is needed. When the pump runs, flow pushes the ball into a pocket in the body, out of the flow path. When the pump stops, the ball falls back into the flow path with the help of the back pressure and blocks any return of fluid to the pump. The ball is steel encapsulated in EPDM. 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 and face-to-face length to DIN 3202. It is a PN10 valve.
