Main features: The valve cover of the low-temperature valve adopts an elongated structure, which aims to protect the packing and packing box, and keep the working temperature of the packing above zero degrees. Prevent valve failure due to the loss of elasticity of the packing during low-temperature operation. The elongated neck design also facilitates insulation work. Mainly used in ethylene, liquefied natural gas plants, 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 low-temperature storage tanks and tank trucks, pressure swing adsorption oxygen production and other devices
