Cryogenic Valves
From WEKA Switzerland, the cryogenic valves regulate the flow of gases such as hydrogen and helium at temperatures ranging from −270°C to approximately −200°C. They are suitable for low-pressure applications up to 40 bar and high-tightness requirements up to 1000 bar. The range includes cryogenic control valves, bellows-sealed cryogenic valves, high-pressure hydrogen valves, shut-off valves, needle valves, and transfer line couplings.
Known for their reliability and durability, the valves are used for the liquefaction and refrigeration of helium and hydrogen, as well as other fluids such as argon, neon, xenon, nitrogen, and oxygen.
