COVNA Swing Type Check Valve (Non Return Valve)
COVNA Swing check valve, also call Non Return valve (NBR). A basic swing type valve consists of a valve body, a bonnet, and a disk that is connected to a hinge. Known as tilting disc check valve, allows full, unobstructed flow and automatically closes as pressure decreases. Usually installed in combination with gate valves because they provide relatively free flow combinations.

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.
