AAP Brass E-Type Check Valve, 2"

This AAP brass E-type spring check valve has a brass CW617N body, a stainless steel spring and an NBR seat. It is supplied in 10 sizes from 3/8" (10mm) to 4" (100mm).

A spring check valve closes with a spring rather than relying on gravity, so it does not need to be mounted upright. This valve can be fitted in a horizontal, vertical or oblique position. Flow opens the disc against the spring, and the spring closes it as flow stops or reverses. Like any check valve it stops reverse flow but it is not a tight shut-off valve, so fit a separate isolating valve where you need to isolate the line. The pressure is 2,482 kPa (24.82 bar) up to 1" and for the 3/8" size, 1,793 kPa (17.93 bar) from 1-1/4" to 2" and 1,172 kPa (11.72 bar) from 2-1/2" to 4". That is higher than the same size of AAP Y-type valve.
