What is a cryogenic valve?
Apply to apply to medium temperature 40 ℃ ~ 196 ℃ - called cryogenic valve valve, cryogenic valves, including low temperature ball valve, gate valve at low temperature, low temperature cut-off valve, safety valve, check valve at low temperature in low temperature, low temperature butterfly valves, cryogenic needle valve, throttle valve at low temperature, low pressure reducing valve, etc., mainly used for ethylene, liquefied natural gas (LNG) plant, gas LPG LNG storage tanks, Accepted base and satellite stations, air separation equipment, 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 medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., is not only flammable and explosive, but also gasification when heating up. When gasification, the volume expands hundreds of times.

The material of liquefied natural gas valve is very important, the material is not qualified, will cause the shell and sealing surface leakage or leakage; The comprehensive mechanical properties, strength and steel of the parts can not meet the requirements of use or even fracture. Causing a leak in the liquefied natural gas medium and causing an explosion. Therefore, in the process of developing, designing and developing liquefied natural gas valves, the material is the first and key issue.

After MANY YEARS of manufacturing, has accumulated rich experience, from the design, technology to manufacturing is increasingly mature, and has developed a series of low temperature valve products.
