Check Valve – KRD-SWS

Wafer-type Non-return check valves with or without spring protecting your system by stopping reverse flow.

A wafer check valve uses a swinging disc to allow or block flow.
Wafer check valves have a molded body that creates space for the disc to fully open, allowing full flow.
When the flow through the valve reverses direction, the fluid pushes the disc back and closes the valve.
Their design allows them to be fitted in extremely tight spaces.
