What is cryogenic valve?
Cryogenic valve refers to the valve with medium temperature ranging from - 40 ℃ to - 196 ℃.
Common Cryogenic valves are divided into Cryogenic butterfly valve, Cryogenic gate valve,Cryogenic ball valve, Cryogenic stop valve,Cryogenic check valve, Cryogenic throttle valve, etc. It is mainly used in ethylene, liquefied natural gas unit, natural gas LPG and LNG storage tank, receiving base and satellite station, air separation equipment, petrochemical tail gas separation equipment, low-temperature storage tank of liquid oxygen, liquid nitrogen, liquid argon and carbon dioxide, tank car, pressure swing adsorption oxygen production device, etc. The output liquid low-temperature medium, such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, is not only flammable and explosive, but also needs to be gasified when heating up. When gasifying, the volume expands hundreds of times.The application of cryogenic valve can control the temperature and prevent explosion and leakage.
