History

50 years "Made in Switzerland"

Our history starts on 31st July 1972 when ADAMS took a share of A. Morel & Söhne AG (AMSAG), a mechanical workshop and manufacturer of steel constructions located in Serneus, Switzerland. After a couple of years the company has been rebranded to ADAMS Schweiz AG.

The company has started to manufacture industrial valves but soon specialised itself in the design and production of valves for hydropower applications. The first hydropower valves in our long history were supplied to local plant operators. These valves have been specially designed according to the customer specific requirements. With this approach we established the basis for our today’s success and expertise. While the first projects have been realized in Switzerland, today our valves prove their quality and reliability in installations all over the globe.
