ASTM A351 CF8 Swing Check Valves, BS 1868, 10 IN, CL600, RF

The ASTM A351 CF8 Check Valves Manufacturer produces high-quality swing check valves designed to BS 1868 standards. These valves feature a cast stainless steel body, providing excellent corrosion resistance and durability. With a 10-inch diameter (DN250) and a pressure class of 600 LB (PN100), they are suitable for a wide range of industrial applications. The raised face (RF) flanged ends ensure secure and reliable connections, making these valves ideal for systems requiring precise control and high performance.

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 their equivalents. These valves are engineered to minimize flow resistance and pressure drop, making them ideal for horizontal installation. The lapped and screwed-in seat ring ensures tight shutoff and long service life. The valve disc is precisely designed, accurately machined, and properly guided for reliable automatic shutoff at zero pressure. The structure is compact and supports low-emission service. In its standard configuration, the swing check valve features a bolted cover and a free-swinging clapper—the closing member that reacts to flow conditions. Swing check valves are most suitable for horizontal pipelines. However, for applications with heavier discs, chattering may occur, in which case dampers or counterweights are recommended.

Product Features

» Non-Return Functionality: Prevents backflow in the pipeline. Flow travels in a straight line through the valve, resulting in minimal pressure drop. The disc swings open with forward flow and seals tightly with back pressure.
» Installation Flexibility: Suitable for horizontal or vertical lines, but must follow the direction indicated by the flow arrow marked on the valve body.
» Optional Accessories: A variety of add-ons are available including bypasses, locking devices, counterweights, and other customer-specific solutions.
