Product Features

» Backflow Prevention: Cast steel swing check valves are designed to prevent backflow in the line, allowing for a smooth, straight-line flow with minimal pressure drop. The disc swings open as the media flows through the valve, while back pressure » holds the disc in the closed position.
» Versatile Installation: These valves can be installed in both horizontal and vertical pipelines. Proper installation requires the valve to be aligned with the flow direction, indicated by the flow direction arrow marked on the body.
» Customizable Accessories: Various accessories, such as bypasses, locking devices, counterweights, and others, are available to meet specific customer requirements, providing flexibility in valve performance and installation.
