Universal Cast Steel Check Valves are meticulously designed and manufactured in strict accordance with International Standards such as API 6D, BS 1868, and ASME B16.34, or their equivalents. These valves are engineered to minimize flow resistance and pressure drop, ensuring optimal performance. They are specifically designed for horizontal installation, with a lapped and screwed seat ring that guarantees a tight seal and long-lasting service. The valve 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 includes a bolted cover and a free-swinging clapper, which acts as the closing member and responds to flow conditions. While swing check valves are ideal for horizontal pipeline installations, heavier disc weights may lead to chattering issues, necessitating the use of dampers or counterweights.

Product Features

» The cast steel swing check valve is designed to prevent backflow in pipelines. The flow through the valve is linear, resulting in minimal pressure drop. The disc swings open as the media flows through the line, and back pressure holds the disc closed.
» Cast steel swing check valves can be installed in horizontal or vertical lines but must be oriented correctly according to the flow direction arrow marked on the valve body.
» A range of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
