Universal Cast Steel Check Valves are designed and manufactured in strict accordance with International Standards such as API 6D, BS 1868, ASME B16.34, or equivalent. These valves are engineered to minimize flow resistance and pressure drop, ensuring optimal performance. They are specifically designed for horizontal installation only. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve’s disc is precisely designed and machined to achieve efficient automatic shut-off at zero pressure, featuring a compact structure and low-emission service. In its standard configuration, the swing check valve has a bolted cover and a free-swinging clapper, which acts as the closing member and responds to flow conditions. Swing check valves are best suited for horizontal pipeline installations. However, for heavier disc weights, chattering issues may occur, necessitating the use of dampers or counterweights.

Product Features

» Cast steel swing check valves are designed to prevent backflow in pipelines. The media flows through the valve in a straight line, resulting in minimal pressure drop. The disc swings open as the media flows through, and back pressure in the line holds the disc closed to prevent reverse flow.
» Cast steel swing check valves can be installed in either horizontal or vertical lines. However, they must be installed in the correct orientation relative to the media flow, as indicated by the flow direction arrow marked on the valve body.
» Accessories such as bypasses, locking devices, counterweights, and other options are available to meet customer requirements.
