Product Features

» Backflow Prevention: The cast steel swing check valve is designed to prevent backflow in the pipeline. The flow moves straight through the valve, minimizing pressure drop, and the disc swings open as the media flows. Back pressure holds the disc in the closed position, ensuring reliable flow direction control.
» Versatile Installation: These valves can be installed in either horizontal or vertical lines, but must be positioned in accordance with the flow direction indicated on the body for proper operation.
» Customizable Accessories: A range of accessories, including bypasses, locking devices, and counterweights, are available to meet specific customer requirements, enhancing the valve’s functionality and adaptability.
