Stainless steel low temperature gate valve DZ41W

Applicable to the medium temperature -40 ℃ ~ -196 ℃ valve called cryogenic valve

Low temperature valve, low temperature valve, low temperature valve, low temperature valve, low temperature valve, low temperature valve, low temperature valve, low temperature valve, low temperature valve, mainly used for ethylene, LNG plant, natural gas LPG LNG storage tank, receiving base and satellite stations, air separation plant, petrochemical exhaust gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low temperature storage tank and tanker, PSA oxygen. The output of liquid low-temperature medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, not only flammable and explosive, but also in the temperature to gasification, gasification, the volume expansion hundreds of times.

Liquefied natural gas valve material is very important, material failure, will cause the shell and sealing surface leakage or leakage; parts of the integrated mechanical properties, strength and rigidity can not meet the requirements and even fracture. Leading to liquefied natural gas leakage caused by explosion media. Therefore, in the development, design, development of liquefied natural gas valves in the process, the material is the primary key issue. After many years of manufacturing, has accumulated a wealth of experience, from design, manufacturing to mature, and has developed a series of low-temperature valve products.

IntroductionThe production of low-temperature valve, the drive can be used manually, worm, pneumatic, electric, connection can be used thread, flange, welding, structure can choose straight-through, sealed structure can choose soft seal, hard seal, pressure range PN0. 1-10Mpa, nominal diameter DN20-400mm, material can choose low-temperature steel, cast steel, brass, stainless steel. As the use of a very wide range of valves, the same valve in different occasions and conditions have different mix, if you are non-professionals, you are welcome to the Company to inquire. The company has professional and technical personnel at your service!Low temperature gate valve Uses:Low temperature gate valve for methane, liquid natural gas, hexene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and other low-temperature mediumLow temperature gate valve features:1, in order to prevent abnormal pressure in the cavity, the inlet side of the gate set pressure relief hole.2, according to the working temperature of the valve to determine the top of the valve cover length to ensure a reliable seal valve stem packing.3, according to the operating temperature of the rational use of fillers, gaskets and other parts of the material.4, strict control of the chemical composition of materials and low temperature impact toughness and other mechanical properties.5, using a variety of pipe flange standard and sealing surface type, suitable for a variety of engineering needs.Low temperature gate valve performance parameters:
