ASTM A351 CF8C Swing Check Valve, API 6D, 10 Inch, CL600, RF

The ASTM A351 CF8C Swing Check Valve Plant produces high-quality swing check valves designed in compliance with API 6D standards. These valves feature a stainless steel body made from ASTM A351 CF8C material, ensuring durability and corrosion resistance. The 10-inch (DN250) valve has a Class 600 LB (PN100) pressure rating, making it suitable for high-pressure applications. The RF (Raised Face) flanged ends provide secure and leak-free connections.

Product Name: ASTM A351 CF8C Swing Check Valve
Design Standard: API 6D
Body Material: ASTM A351 CF8C
Size: 10 Inch, DN250
Pressure: Class 600 LB, PN100
End Connection: RF Flanged

Our Universal Cast Steel Check Valves are engineered to meet international standards such as API 6D, BS 1868, ASME B16.34, and equivalents. These valves are designed to minimize flow resistance and pressure drop, ensuring efficient performance. They are intended for horizontal pipeline installation only and feature a lapped and screwed-in seat ring for a tight shutoff and long service life. The valve's disc is meticulously designed and machined to provide effective automatic shutoff at zero pressure. The swing check valves come with a bolted cover and a free-swinging clapper, responding to flow conditions for optimal sealing. However, for applications with heavier disc weights that may cause chattering, dampers or counterweights may be necessary to ensure smooth operation.

Product Features

» Efficient Flow Control: Our cast steel swing check valve is designed to prevent backflow in pipelines. The valve allows fluid to flow in a straight line, minimizing pressure drop and ensuring smooth operation. The disc swings open as the fluid moves through the line, and it closes securely under back pressure.
» Flexible Installation Options: These cast steel swing check valves can be installed in both horizontal and vertical lines. For optimal performance, ensure the valve is positioned correctly according to the flow direction arrow marked on the body.
» Customizable Accessories: A range of accessories, including bypasses, locking devices, counterweights, and more, are available to meet your specific needs and enhance the functionality of the valve.
