Ultra-low Temperature Ball Valve

Main features: The valve stem neck of the cryogenic valve adopts an extended structure, the purpose of which is to protect the packing and stuffing box, so that the working temperature of the packing is above zero degrees. It prevents the valve from failing due to the loss of elasticity of the packing under low-temperature operation. The extended neck design is also convenient for heat preservation operation. It is mainly used in ethylene, liquefied natural gas equipment, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tanks and tank trucks, pressure swing adsorption oxygen production equipment, etc.
