Main Features: The valve cover of the cryogenic valve adopts an extended structure, aiming to protect the packing and the packing box, ensuring that the working temperature of the packing remains above zero degrees. This prevents the loss of elasticity of the packing under low-temperature operations, which could lead to valve failure. The extended neck design also facilitates insulation work. It is mainly used in ethylene, liquefied natural gas installations, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation plants, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low-temperature storage tanks and tankers, pressure swing adsorption oxygen generation, and other installations.
