Extended Bonnet Globe Valves, ASME B16.34, CF8, 6 IN, 150 LB

The Extended Bonnet Globe Valve is a cryogenic valve designed for extreme low-temperature applications, specifically for environments below -196°C. Constructed from ASTM A351 CF8 stainless steel, it ensures excellent corrosion resistance and durability. Compliant with ASME B16.34 standards, this 6-inch (DN150) valve operates at a Class 150 LB pressure rating. With an extended bonnet design, it effectively accommodates temperature fluctuations, making it ideal for cryogenic systems in industries such as LNG, chemical processing, and aerospace.

The Cryogenic Globe Valve is specifically designed to handle low-temperature and cryogenic conditions, with robust construction using materials like stainless steel, carbon steel, and cast steel. It features an extended bonnet, the length of which is customizable based on the application and user specifications. This extended bonnet ensures the stem packing is kept at a safe distance from the cryogenic fluid. The valve is ideal for applications involving cryogenic fluids with temperatures as low as -196°C and is commonly used in gas/terminal production plants, ethylene plants, and LNG (Liquefied Natural Gas) systems. We offer a range of globe valves designed to perform reliably across different applications.
