About Us
AAS GmbH Armaturen Anlagen Service, headquartered in Wesel, manufactures and tests valves for industry, power plants and process engineering. The portfolio includes standard and special valves such as steam conversion and steam control valves, minimum-flow and water control valves, high-pressure gate valves, high-pressure check valves, safety relief stations as well as patent-pending developments such as the Type AGBS housing overpressure protection device and the ARED-V straight-through valve. In addition to manufacturing, the company offers engineering services for valves, valve testing and a comprehensive valve service. Production is carried out in heat-resistant steels and stainless steels such as C 22.8, 16Mo3, 10CrMo910, X20CrMoV121 or X10CrMoVNb91 for temperatures up to +650 °C and pressures up to PN 500. Manufacturing is performed, among others, in accordance with DIN EN ISO 9001, AD 2000, PED 2014/68/EU and ASME B16.34. In addition to its headquarters in Wesel, the company is represented by a certified site in Kahl am Main.
