ASTM A351 CF8M Wedge Gate Valve, API 600, 10 Inch, CL600, RF

The China ASTM A351 CF8M Gate Valve Factory specializes in manufacturing high-quality wedge gate valves designed to API 600 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 well-suited for demanding industrial applications. The bevel gear operation ensures smooth and reliable valve control. The valves are equipped with raised face (RF) flanged ends for secure and leak-tight connections, making them ideal for systems requiring high performance and reliability.

Cast Steel Gate Valves are engineered to provide exceptional sealing performance, limiting leakage of volatile organic compounds (VOCs) to less than 100 ppm. Through extensive laboratory testing, including static and cycle evaluations, has established essential design parameters to ensure low-emission performance in both the stem packing and bonnet gasket sealing areas. In-house quality control procedures are strictly implemented to maintain consistent product quality, ensuring every gate valve complies with the ≤100 ppm VOC leakage requirement prior to delivery.
