Hydrogen pressure relief valve – series 492

  • Goetze’s hydrogen high-pressure relief valve from 50 to 1500 bar.
  • A pressure relief valve of impressive compactness and design with flexible and rotatable outlet body in gas-tight design for controlled outflow or for connection of a blow-off line for non-neutral gaseous media.
  • Remains tight even after repeated opening and closing.
  • Our pressure relief valve is used to prevent excess pressure of the vessels in high pressure applications and prevent the further release of gases after normal conditions have been restored.
  • These are test approved safety valves with EU-type examination and TÜV approval for high pressure hydrogen applications.
  • This allows the use of tested and approved quality on the high pressure tanks.
  • The discharge safety valves are made of stainless steel (1.4404/316L; 1.4408/CF8M), angle-type with threaded connections or standard threaded connections.
