​Cryogenic valves

Cryogenic valves suitable for medium temperature -40℃ ~ -196℃ are called cryogenic valves.
Cryogenic valves include low temperature ball valve, low temperature gate valve, low temperature globe valve, low temperature safety valve, low temperature check valve, low temperature butterfly valve, low temperature needle valve, low temperature throttle valve, low temperature pressure reducing valve, etc. Cryogenic valves are mainly used in ethylene, liquefied natural gas installation, natural gas LPG LNG storage tank, acceptance base and satellite station, air separation equipment, etc. Petrochemical exhaust gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low temperature storage tank and tank truck, pressure swing adsorption oxygen production equipment. The output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., are not only flammable and explosive, but also gasification when heating up, and the volume expands hundreds of times when gasificatio
