The use of gas recovery systems in cryogenics helps to save costs by carrying the evaporated fluid into a collection system. In order to prevent the gas from flowing back into the primary circuit, check valves with a very low response pressure should be used. Typical applications concerned are gases such as He, Ne, H2, N2 or Ar.
Valve characteristics
WEKA check valves of the ClpdV type are typically used for gases such as He, Ne, H2, N2 or Ar. They are designed for a nominal pressure PN of 4 bar and for a temperature range of -20 °C to 60 °C. Standard versions are the nominal diameters DN25, DN40 and DN50 with a vacuum KF flange connection. Larger nominal diameters or other connection versions,...
