Flanged hydrogen pressure relief valve – series 455

  • Our flanged pressure relief valves is used to prevent excess pressure of the vessels in different applications and prevent the further release of gases after normal conditions have been restored.
  • These are test approved flange safety valves for hydrogen applications.
  • This allows the use of tested and approved quality on pressure tanks and pressurized systems with neutral and non-neutral gas and liquid mediums.
  • The safety valves are made of stainless steel (1.4404/316L; 1.4408/CF8M) and standard flange connections.
  • By using exclusively high-quality materials with outstanding media resistance and the option to protect the tightness towards the atmosphere on a high level with backpressure compensating
    bellows, this safety valve is suitable for high tight hydrogen applications.
