Product Features

» Preventing Backflow: The cast steel swing check valve is designed to prevent reverse flow in the pipeline. It allows fluid to flow in a straight line through the valve, resulting in minimal pressure drop. The disc swings open as the fluid flows through, and it closes when back pressure is present.
» Flexible Installation: Cast steel swing check valves can be installed in both horizontal and vertical pipelines. However, they must be positioned correctly according to the flow direction, as indicated by the arrow marked on the valve body.
» Customizable Accessories: A variety of accessories are available to meet specific customer needs. These include bypasses, locking devices, counterweights, and more.
