Product Overview of Cryogenic and High-Pressure Solenoid Valves

Cryogenic and high-pressure solenoid valves are suitable for working conditions with a medium temperature ranging from -196℃ to 60℃. They are generally used in cryogenic systems such as liquid helium, liquid hydrogen, liquefied natural gas (LNG), and air separation. The applicable media include cryogenic fluids like liquid helium, liquid hydrogen, LNG, liquid nitrogen, and liquid oxygen.
