Cryogenic Valve Profile
Cryogenic valve including cryogenic ball valve, cryogenic gate valve, cryogenic globe valve, cryogenic check valve, cryogenic butterfly valve, cryogenic needle valve, mainly used in ethylene, liquefied natural gas plant, natural gas LPG LNG storage tank, receive bases and satellite stations, air separation plant, petrochemical exhaust gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tank and tank car, psa oxygen generator production equipment.
The liquid output cryogenic medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products and so on, not only flammable and explosive, but also vaporizes when heating up. When vaporizes, the volume expands hundreds of times. The application of cryogenic valve controls the temperature and prevents hidden dangers such as explosion and leakage.
- Low temperature resistant material
- Excellent sealing performance
- Quick response
- Lightweight design
- Long axis valve design
6 Key Features of Cryogenic Valve
Excellent low temperature resistance
- The cryogenic valve is made of materials suitable for cryogenic environment, such as SS, aluminium alloy etc., these material still can maintain good toughness and mechanical properties to avoid brittleness.
- Special material handling and heat treatment to ensure that valve do not lose physical and chemical properties at extremely cryogenic environment.
High seal performance
- The cryogenic valve sealing is machined precisely, and use high performance seal material, such as PTFE and graphite, which can ensure excellent sealing performance at cryogenic environment.
- The effect of low temperature on material size change is considered in valve design, leave appropriate gaps to avoid leakage caused by thermal expansion and contraction.
High reliability
- The cryogenic valve is under strict quality control during design and manufacturing, including material inspection, process control and inspection test etc., to ensure that each step can achieve high standard.
- The cryogenic valve will carry out a series of pressure tests, leakage test and functional test before they go out, which can ensure reliability and stability in actual application.
Flexible Operation
- The design considering convenient operation, no matter manual or automatic operation, can achieve the open and close action easily.
- Some advanced cryogenic valve are also equipped with electric, pneumatic or hydraulic actuator, further increase the level of flexibility and automation of operation.
Wide Range of Application
- Cryogenic valve is widely used in petroleum, chemical, electric power, metallurgy, shipbuilding, water treatment and other industries, especially in the transportation and storage systems of liquefied natural gas (LNG) and cryogenic fluids such as liquid oxygen and liquid nitrogen.
-No matter transport liquid, gas or steam, the cryogenic valve can provide reliable solutions.
Maintenance Friendly
- Simple structure design, easy to disassembly and assembly, regular inspection and maintenance conveniently.
- When a failure does occur, it can replace damaged parts to recovery function reduce maintain cost and time
