About us

aas GmbH Armaturen Anlagen Service was founded in 2011 with a focus on valve service. Since 2019 we are also a successful and certified manufacturer of new valves. At the headquarters in Wesel on the Lower Rhine and the sales office in Kahl am Main, we serve well-known customers from the energy sector and industry throughout Europe.

As a manufacturer of high-pressure valves with a comprehensive program for standard and special valves, aas GmbH offers industry know-how with over 40 years of experience. With our technological innovations and own patents, we provide our customers not just any result, but an individual solution that suits them well.



As before, we are also the right contact for revision planning, maintenance and repair, reproduction of required spare parts and rebuilding of valves. We also take care of the periodic inspection of safety valves (online testing), which we perform without disturbing the plant during normal operation. And this for all manufacturers and brands.
