Product Features

» Cast steel swing check valve is used to prevent backflow in the line. Flow is in a straight line through the valve, resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line, and back pressure in the line holds the disc in the closed position.
» Cast steel swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
» Accessories such as bypasses, locking devices, counterweights, and many others are available to meet the customers’ requirements.
