In 1966 the company was founded in the district Spradow of the westphalian village Bünde. In the beginning we were an industrial plant implying automatic lathes.
Since 1974 we were already in the line for test valves for vehicle breaks following the specification of our clients.
In 1980 test couplings for high pressure hydraulics were added to this production program.
During the following years we were busy covering the construction of both areas of our program - pneumatic and hydraulic - and completing their production range.
In addition to that we have developed fitting devices which rendered the assembly of large quantities possible.
In 1987 we moved the company's location from Bünde to Schloß Holte-Stukenbrock.
During the last years, through mutual support between us and our customers, we acquired a complete product range of test valves and coupling.
In addition to domestic sales we have a net of wholesalers who are currently supplying the following countries:
Austria, Belgium, Finland, France, Great Britain, Hongkong, Italy, India, Kingdom of Saudi Arabia, Netherlands, Norway, Sweden, Switzerland, USA and Canada.
