Check Valve
Crown Wafer Check Valve
Wafer Check Valve
Wafer check valve use a swinging disc to allow or block flow. Their design allows them to be fitted in extremely tight spaces – where the flanged check valve can not be used. The wafer check valves have molded bodies around the area where the disc opens up. Suitable for horizontal or vertical flow-up service
