ADAMS Schweiz AG has evolved from the former AMSAG company and has been manufacturing butterfly valves for the most diverse applications since 1979. Located in the beautiful village of Serneus, the company has set a specified focus in development and production of closures for hydropower next to the production of industriel valves. The company is both looking back and forward to many years of success. Quality in conjunction with optimal service and support has always been the key to our success.


Turbine Inlet Safety Valves

The safety valves are mainly steel-welded with hydrodynamically optimized valve discs, in monoplane or bi-plane designs. The valves are supplied with hydraulic servomotors as the opening mechanism and a lever with counterweight for forced closing. For special applications, ADAMS offers a range of other actuation mechanisms. The valves are supplied with all the accessory parts required for smooth operation.

Spherical Valves

Spherical valves are installed as special shut-off valves for high pressures at the end of the penstock in front of the turbine. Their main purpose is to shut-off the penstock during normal shutdown or in the case of turbine trips.
