How to choose the valve of the cryogenic tank

Different media, different temperatures, different environments, etc. determine what kind of valve to use. When selecting a valve, the lowest cost and easiest operation are the basic factors.
 
For the majority of consumers, how to properly choose the type of cryogenic liquid storage tank valve is a headache. Here is a brief description of how to properly select a cryogenic tank valve.
 
The low temperature storage tank valve refers to the control valve which is made of low temperature steel and the stem is lengthened. Generally, the common low temperature media are: liquid oxygen, liquid nitrogen, liquid hydrogen, liquefied natural gas, liquefied petroleum gas, etc. The low temperature valve generally has a minimum temperature resistance range of -196 ° C. When selecting a liquid cryogenic storage tank valve, you must first clearly understand the medium and temperature used, and secondly you must clearly understand what the actual effect of the cryogenic valve is after installation. According to the requirements of the cryogenic valve, a reasonable choice of cryogenic valve Types of.
 
Valves for low-temperature liquid oxygen, liquid hydrogen, liquefied natural gas, and liquefied petroleum medium are used for on-off valves. The main choices are low-temperature shut-off valves and low-temperature ball valves. Valves for regulating the pressure, temperature, and flow of low-temperature liquid oxygen, liquid hydrogen, liquefied natural gas, and liquefied petroleum media. Select low temperature check valve for preventing low temperature liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum medium from flowing backward. Used to protect the safety of low-temperature liquid storage and transportation equipment. When the pressure reaches a certain value, it is safe to discharge. A low-temperature safety valve should be selected.
