COVNA Swing Type Check Valve (Non Return Valve)

Swing check valve uses a swinging disc to allow or block flow and are not designed for extremely tight spaces. The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve.

The swing check valves functions by allowing flow forces to move the closure element, it is a hinged clapper which wings or rotates around a supporting shaft.

The disk swings away from the valve-seat to allow flow in the forward direction, and returns to the valve-seat when upstream flow is stopped, to prevent backflow.
