Product Features

» Backflow Prevention: The cast steel swing check valve is designed to prevent reverse flow in the pipeline. Its straight-through flow path minimizes pressure drop. The disc swings open as the media flows through the line, while back pressure holds the disc in the closed position.
» Flexible Installation: Cast steel swing check valves can be installed in both horizontal and vertical pipelines. However, they must be oriented correctly according to the flow direction arrow marked on the valve body.
» Customizable Accessories: A variety of accessories, including bypasses, locking devices, counterweights, and other options, are available to meet specific customer requirements.
