Cast Steel Swing Check Valves, API 6D, BS 1868, WCB, 10 Inch

The Cast Steel Swing Check Valves are high-performance industrial valves designed to prevent backflow in pipelines. These valves comply with API 6D and BS 1868 standards, ensuring reliability and durability. Made from carbon steel ASTM A216 WCB, they feature a robust construction suitable for demanding applications. With a nominal pipe size of 10 inches (DN250) and a pressure rating of 600 LB (PN100), these valves are built to handle high-pressure conditions. They come with a bolted cover and RF flanged ends for secure and easy installation.

Universal Cast Steel Check Valves are engineered and produced in strict compliance with international standards such as API 6D, BS 1868, ASME B16.34, or equivalent. These valves are designed to minimize flow resistance and pressure drop, ensuring optimal performance. They are specifically intended for horizontal installation. The lapped and screwed seat ring guarantees a tight seal and long-lasting service. The valve disc is meticulously designed and machined to provide efficient automatic shut-off at zero pressure. The valves feature a compact structure and low-emission service capabilities. In their standard configuration, swing check valves include a bolted cover and a free-swinging clapper, which acts as the closing member and responds to flow conditions. While these valves are ideal for horizontal pipeline installations, heavier discs may cause chattering issues. In such cases, dampers or counterweights should be installed to mitigate these problems.

Product Features

» Preventing Backflow: The cast steel swing check valve is 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.
