Built In Wafer Check Valves

CHAODA Valves Group is specialized in manufacturing Built In Wafer Check Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Wafer Type Check valve, also known as one-way valve, non-return valve and so on,  is an automatic valve whose opening and closing is by the force of flowing medium. The function of Wafer Type Check Valve is to allow the flowing medium in one direction and prevent its back flow.

The discoid shape disc of  Wafer Type Check valve does its swing movement around the hinge. Wafer type check valve has a streamlined passage with smaller flowing resistance than Lifting check valve, and this makes it suitable for large diameter situation with low speed and relatively steady flowing medium,but not for pulsating medium. However, the sealing performance of wafer type check valve is not as good as Lifting type. Wafer type check valve could be divided into single disc, twin plates type and multi plates type, all of which are used to reduce the water hammer shock when medium back flows.
