Powerful manifold pressure regulator to regulate high flows at acetylene cylinder manifolds or bundles (packs).


  • extremely low-pressure drops (Δp) provide optimal draining of the manifold or bundle > see dynamic expansion curve
  • integrated relief valve (according to ISO 7291)
  • 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


  • The ADR 150 for acetylene is used to reduce high pressure to working pressure in acetylene supplies as required in EN 14114.
  • Given the high regulating accuracy and flow specifications, it is suitable for all applications with high pressure requirements.


  • The 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).


  • It is recommended that a leak check concerning the atmosphere is conducted at regular intervals.
  • Repairs are only to be carried out by the manufacturer.
