Introduction to Cryogenic Valves
Cryogenic valves are specialized valves designed to operate in extremely low - temperature environments, typically below -40°C. These valves are crucial components in industries such as liquefied natural gas (LNG), liquid oxygen, liquid nitrogen, and other cryogenic applications. They must be able to withstand the challenges posed by low temperatures, including material brittleness, thermal contraction, and the need for tight sealing to prevent leakage of cryogenic fluids, which can be both dangerous and costly.
