Check valves


Check valves seem to be simple, passive elements. In the context of cryotechnology, however, their production is very demanding. In a cryogenic plant, check valves are used inside the vacuum insulation without access.

They are therefore mounted at the beginning and have to work for 20 or 30 years without maintenance.

The function of clean and sound-free opening in one direction with shut-off in the opposite direction as well as the leak-tightness requirement for helium must be implemented in a component which is not subject to wear.

In addition to a complete range of cryogenic check valves, WEKA also offers check valves with extremely low set pressure for gas recovery systems as well as tailor-made solutions for high pressure applications.
