Protect the superfluid helium enclosures of superconducting magnets against over-pressure resulting from resistive transitions (Quench) as well as some of the cryogenic lines (QRL). ● Downstream pressure does not affect the set pressure ● Very low heat inleak ● Resistant to radiation
  • Superfluid helium service

  • Cold box adaptation

  • Single or double bellows sealed

  • Remote control actuation (on/off function)

  • No risk of icing or jamming when operating
