In 1939, Alfred Konrad founded a manufacturing company for machining and apparatus engineering in Bochum, which produced, among other things, conveyor belts and wheel discs for rail transport.

As a contract manufacturer, the young company benefited from the upswing of the economic miracle years after the end of the war. With the development of high-quality industrial valves, the company launched its own product on the market at the end of the 1960s, thus laying the foundation for steady growth in the following decades.

EXENTROMAT® industrial valves
Thanks to a double eccentric disc positioning with simultaneously improved sealing geometry, a highly resilient metal-to-metal seal was made possible for the first time.

With this design in high-quality welded construction, customised KONRAD Armaturen have become renowned worldwide under the protected trademark EXENTROMAT® since then.
