Occasionally we supply gasket sets for the mixing valves, which our founder Heinrich Janssen has made 50 years ago. It appears that „JAnssens STahlgeschweißte Armaturen“ kept their promise of high quality standards.

Inventive genius meets the right moment

In the early 1960s the Ruhr region flourished as an industrial location and thus also the need for housing for the workers. JASTA satisfied the growing demand for mixing valves for heating systems. Heinrich Janssen did not want to solely react. With his fondness for experimenting and the will to innovate, he laid the foundation for the company, which still successfully cultivates these qualities: Janssen developed low maintenance valves that allowed a replacement of the gasket during operation. Thanks to this invention, heating systems could be maintained at significantly lower expenses. Subsequently JASTA grew rapidly and sold its valves throughout Europe and even as far as Asia.

Sound foundation for turbulent times

In 1967 JASTA needed more space, so Heinrich Janssen rented the mechanical maintenance department at the premisses of the former coal mine Levin in Essen-Dellwig. One year later he bought the 300 m² hall including 2500 m² site. Periodic reconstructions of factory buildings and acquisitions of adjacent sites followed. As the current CEO Jürgen Hengst joined JASTA in 1967 as a commercial trainee, the company had about a dozen employees, consisting of businessmen, technicians and metalworkers.

Adverse business fluctuations and major economic crises JASTA encountered with the proven virtues innovation, flexibility and reliability. At times, the company even subsisted on contract work. At the same time the valves were constantly developed and adapted to new requirements, such as electrical and pneumatic actuation. Thereby JASTA succeeded in entering the market as an original equipment manufacturer for the industry.

At the beginning of the 1990s, Heinrich Janssen won his managing director Jürgen Hengst around to become an associate. The plant construction projects became more sophisticated and JASTA for the first time hired engineers. Sales representatives and partner companies began to distribute the customized valves in large diameters and for high temperatures to outside Europe.

History to be continued

At present JASTA develops as a modern medium-sized company following the tradition of its founder Heinrich Janssen. Reliable solutions are designed and assembled by an international staff at the continuously expanding site in Essen. Introducing new product lines, the company is prepares for the needs of the industries of the future.
