Dome pressure regulator ADR 150 consists of a pilot pressure regulator (pilot gas = shielding or inert gas) in combination with a dome loaded pressure regulator and a relief valve. The required pipeline pressure is adjusted by the pilot pressure regulator to a maximum of 1.5 bar (2 bar available on request).


  • extremely low pressure drops (Δp) provide optimal draining of the manifold or bundle > see dynamic expansion curve;
  • the only one in the world with:
    - 50 m3/h flow capacity; 
    - extremely stable outlet pressure;
  • integrated relief valve, pilot pressure regulator with pressure gauge and outlet pressure gauge.
