We are an innovative manufacturer of high-pressure valves with a comprehensive program for standard and special valves. With our special branch know-how from over 40 years of experience we serve well-known customers from the energy sector and industry throughout Europe. Thanks to technological innovation, our own patents and state-of-the-art advancement, we have quickly established us at the top of the market for high pressure valves. We take over the design and manufacture of new valves for you, which are of course produced in Wesel according to the applicable regulations such as DIN EN ISO 9001, AD 2000, PED 2014/68/EU. However, we are also your contact partner for planning revisions, maintenance and repair of your valves and the reproduction of required spare parts. We also take care of the recurring testing of your safety valves (online testing), which we perform without disturbing the plant during normal operation. Modern waste incineration plants, gas and steam combined cycle power plants, biomass power plants and of course industrial plants achieve today an unprecedented efficiency – not only, but also thanks to the aas GmbH at its side.
