BS 1868 Swing Check Valve, ASTM A216 WCB, 14 Inch, CL600, RF

The BS 1868 Swing Check Valve is a high-quality industrial valve designed for reliable flow control. Manufactured with a carbon steel ASTM A216 WCB body, it features a robust construction suitable for demanding applications. The valve has a 14-inch diameter (DN350) and is rated for a pressure class of 600 LB (PN100), ensuring it can handle high-pressure conditions. It comes with a bolted bonnet and RF flanged ends for secure and easy installation.

Universal Cast Steel Check Valves are meticulously designed and manufactured in strict adherence to international standards such as API 6D, BS 1868, ASME B16.34, or equivalent. These valves are engineered to minimize flow resistance and pressure drop to the greatest extent possible. They are specifically designed for horizontal installation only. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve disc is perfectly designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure. These valves feature a compact structure and low-emission service capabilities. In their standard configuration, swing check valves come with a bolted cover and a free-swinging clapper, which acts as the closing member and responds to the prevailing flow conditions. While swing check valves are best suited for horizontal pipeline installations, heavier discs may cause chattering issues. In such cases, dampers or counterweights should be provided to address these problems.

Product Features

» Backflow Prevention: The cast steel swing check valve is specifically designed to prevent backflow in pipelines. It allows media to flow in a straight line through the valve, resulting in minimal pressure drop. The disc swings open as the media flows through the line and 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 installed in the correct orientation relative to the media flow, as indicated by the flow direction arrow marked on the valve body.
» Customizable Accessories: A variety of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
