Non-Return Valve / Cast Iron Check Valve
This type of valve restricts the flow of the medium in one direction only. The valve disc is kept in open position by the flow medium and any reverse flow causes the disc to close preventing reflux of flow. The valve operating depends on the velocity of the flow.
