ASTM A351 CF8 Cryogenic Globe Valve, BS 1873, DN65, PN20, BW

The ASTM A351 CF8 Cryogenic Globe Valve Supplier offers high-performance cryogenic globe valves designed to meet the BS 1873 standard. These valves feature a cast stainless steel body made from CF8 material, ensuring excellent corrosion resistance and durability in low-temperature applications. With a DN65 (2-1/2 inch) size and a pressure rating of PN20, they are suitable for handling cryogenic fluids such as LNG (liquefied natural gas), LO2 (liquid oxygen), LN2 (liquid nitrogen), LAr (liquid argon), and CO2 (carbon dioxide). The valves have butt-welded ends for seamless integration into cryogenic systems.

The cryogenic globe valve is specifically designed to perform reliably under low-temperature and cryogenic conditions. Constructed from durable materials such as stainless steel, carbon steel, and cast steel, it features an extended bonnet that protects the stem packing by distancing it from the cryogenic medium. The length of the bonnet varies depending on the application and user requirements. These valves are commonly used in LNG facilities, ethylene plants, and gas production terminals, and are capable of throttling fluids at temperatures as low as -196°C. We offer a wide range of high-performance cryogenic globe valves tailored to meet diverse industrial needs.
