Swing Check Valve

A simple swing check valve is made up of a valve body, a bonnet, and a disc attached to a hinge. When the flow is stopped, the disc swings back onto the seat to impede backward flow. The disc swings off the seat to allow forward flow. The valve’s ability to shut off is influenced by the disc’s weight and the return flow. In order to enable flow in the forward direction and to avoid backflow, the disc swings away from the valve-seat.
