PRESSURE REGULATOR ADR 150 for acetylene Powerful manifold pressure regulator to regulate high flows at acetylene cylinder manifolds or bundles (packs). Benefits • extremely low pressure drop (Ap) 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 - 150 m3/h flow capacity - extremely stable outlet pressure • integrated relief valve, pilot pressure regulator with pressure gauge and outlet pressure gauge Operation / Usage 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. Function 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). Maintenance It is recommended that a leak check to atmosphere at regular intervals be conducted. Repairs are only to be carried out by the manufacturer.
