Product Features

» Backflow Prevention: The cast steel swing check valve is designed to prevent backflow in pipelines. The flow moves in a straight line through the valve, resulting in minimal pressure drop. The disc swings open as media flows through, and back pressure keeps the disc closed.
» Versatile Installation: Cast steel swing check valves can be installed in both horizontal and vertical pipelines. Proper installation should follow the flow direction indicated by the arrow on the valve body.
» Customizable Accessories: A variety of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
