Crane Cast Steel Swing Check Valves are designed to open by the system pressure in a line. The normal direction of flow in the line will open the valve, and any attempt by the flow to reverse will close the valve completely. The check valve typically does not require any outside force or signal to operate properly. Check valves allow flow in one direction only.
