An international company since 1969.

Our success story began with the trade and distribution of valves and accessories. Accessing international markets was part of our strategy right from the start. The cornerstone for international expansion was laid with the opening of our first branches in Austria and Italy.

 In-house development, in-house manufacturing.

We began to develop and produce our first butterfly valve to our own design in Switzerland very early on. To meet the high demand, we opened an additional manufacturing site in Spain. Today, we offer you both our own and InterApproved commercial products.

Our employees make the difference.

Our motivated employees are a vital factor in our success in the areas of development, manufacturing, quality control and logistics, sales, administration, and project management in all our markets.
