cryogenic ball valves are designed for cryogenic applications where conventional ball valves cannot be used. and mainly applicable to ethylene, liquefied natural gas, and other chemical devices, and the output liquid low-temperature media such as ethylene, liquid oxygen, and liquid hydrogen. This kind of medium is not only flammable and explosive but also needs to be gasified when heating up. When gasified, the volume expands hundreds of times
