Welcome to aas GmbH

aas GmbH is a manufacturer of high-pressure valves. We support our customers with isolation valves, control valves, steam-converting valves and turbine bypass stations. They are used in power plants, industrial steam plants and process engineering. 

aas GmbH was founded in 2009 by former technical and commercial employees of the worldwide renowned C.H. Zikesch GmbH from the city of Duisburg. C.H. Zikesch GmbH has been a global leader for over 45 years in manufacturing high-pressure valves. All of these valves have been designed and manufactured to customer specification. 

Through technological innovation and further modern development, aas GmbH has taken a leading position in the market for high-pressure valves. An exceptionally low-noise steam-converting valve and a steam-converting valve with ultrafast temperature control are only two of these innovative products.

As of March 2019, aas GmbH produces high-pressure valves based on the knowhow of C.H. Zikesch GmbH employees as well as other well-known companies. Of course all our high-pressure valves are produced in accordance with regulations such as DIN EN ISO 9001, AD 2000 and PED 2014/68/RU in the city of Wesel. 

Common values for all our customers are reliability, durability and perfect suitability for each application. This is just what we offer. We have always manufactured customer-specific products and innovative solutions in the valve segment. Operators rely on the safety of our valves. Fossil power plants that are complemented by regenerative energy sources are in demand of durable materials in order to shut down and start quickly. Operators of such plants rely on us as specialists in valve manufacturing. Yet we do not only adapt to change but also shape the future. 

State-of-the-art incineration plants, steam and gas combined power plants and biomass power plants have an unprecedented degree of efficiency. Through our products we contribute to these results. 

ARED-V

Just recently we filed a patent application for the world’s first high pressure shut-off, drainage and control valve that ist wear-free and without pressure loss.

For us, our quality standards are the top priority of the company.
