Weka AG

Bellows valve 4K

WEKA check valves of the CCV type are typically used for liquefied gases such as He, Ne, H2, N2 or Ar. They are designed for a nominal pressure PN up to 25 bar and for a temperature range from 4 K to 323 K. Standard versions are the nominal diameters DN6 to DN200 and with weld-on ends, optionally with extensions or also with flanges.

In order to avoid undesired oscillations in the system, the check valves can also be designed with a small seat bypass borehole.
