Product Features

» The Cast Steel Swing Check Valve is designed to prevent backflow in pipelines. The valve allows flow in a straight line, minimizing pressure drop. The disc swings open as the media flows through the line, and back pressure ensures the disc remains in the closed position when necessary.
» Cast Steel Swing Check Valves can be installed in both horizontal and vertical pipelines. However, correct installation in relation to the flow direction is crucial, as indicated by the flow direction arrow on the valve body.
» A wide range of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
