The prime functin of a check valve is to protect mechanical equipment in a piping system by preventing reversal of flow by the fluid which means the check valve is an automatic valve with forward flow and close againgst reverse flow. The closure member of swing check valve swings about a hinge, which is which is mounted outside the seat.
