Swing Check Valve Threaded 200 WOG general situation

Check Valve, also known as a one-way valve or Check Valves.
The swing check valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The movable part to block the flow, swings on a hinge, either onto the seat to block reverse flow or off the seat to allow forward flow. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position.
Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
The swing check valves is a flap valve around the sealing surface for rotating movement, resistance than elevating small, poor sealing performance.
