Hydroelectricity safely under control

Located in the central Alps, our plant in Serneus in the Swiss canton of Graubünden has developed to become a specialist supplier of valves for hydroelectric power stations over the decades. Today customers worldwide make use of our know-how in order to install reliable safety valves in hydroelectric power stations. ADAMS SCHWEIZ AG has produced valves for hydroelectric power stations at its 8,000-square-metre premises since 1972. Due to its topography and the high average precipitation, Switzerland has a long tradition in the use of hydroelectric power.

Today Switzerland generates 56% of its energy from hydroelectric power. Switzerland’s hydropower network consists of over 540 hydroelectric power stations. This environment has always offered us the ideal situation in which to develop perfectly coordinated solutions for the requirements of safety valves for hydroelectric power stations.

Our employees in Switzerland are our guarantee of the highest quality and precision. Just like at our other locations, our staff have remained loyal to the company over many years, ensuring a high degree of commitment and experience. Apart from manufacturing valves, we also provide our customers with help when planning new plants or modernising and refurbishing existing plants. The latter point is a key task in view of the need for carbonoptimised energy generation.

Safety for hydropower plants from the Grison in the Swiss Alps

Hydropower makes an indispensable contribution to safe, environment friendly generation of electric
power. The fate of both today‘s world and of the future depends on having a secure energy supply from
hydropower plants that are dependable and operational at all times. Analogous to other new sources
like wind and solar power, pumped-storage plants are growing in significance as a reliable, swift source
of energy with a large storage potential.

Safety remains in the foreground when it comes to hydropower plants. Valves and shut-off equipment that
are dependable and durable play a vital role to that end. Since 1972, we have been developing, building
and examining a product line featuring valves and shut-off equipment tailored to customer needs for hydropower
plants. Over that time, our products have been installed all over the world and demonstrated their
reliability on a daily basis over the course of decades.

The Prättigau Valley in the Grison is exemplary for the close expertise our hydropower specialists have to
the specific requirements pertaining to hydropower plants in alpine areas. Whether the project involves
producing new valves or modifying existing ones: We develop complete, individualised solutions optimally
tailored to the customer‘s operational requirements and the hydro plant‘s design.
