cryogenic high-pressure globe valve

The cryogenic high-pressure globe valve is specifically designed for applications involving extremely low temperatures and high pressures. Constructed with stainless steel or other cryogenic-grade materials, it ensures reliable performance in temperatures as low as -196°C. The valve features a precision-machined sealing surface, providing tight shutoff and leak-free operation under high-pressure conditions. Its extended bonnet design prevents frost damage and ensures thermal insulation of the stem area. This valve is ideal for industries such as liquefied natural gas (LNG), air separation, and cryogenic chemical processing. With excellent resistance to thermal shock and corrosion, the cryogenic high-pressure globe valve guarantees safe and efficient fluid control in demanding environments.

Description
