AAP Resilient Swing Check Valve, 4"

This AAP resilient seat flanged swing check valve has a cast iron body, cover and disc, an EPDM disc trim, a bronze body trim and flanges to AS 2129 Table E. It is supplied in 9 sizes from 2" (50mm) to 12" (300mm). A resilient seat swing check valve lets flow through in a nearly straight line and closes by swinging a hinged disc, here fitted with an EPDM disc trim, against the seat when flow reverses. It can be fitted with a counter lever and weight.

The maximum working temperature is 120°C and the cold working pressure is 1,600 kPa (16 bar), with flanges to AS 2129 Table E. The 2-1/2" valve weighs the same, 14kg as the 2" valve.
