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.
