In 1967, JASTA needed more space, so Heinrich Janssen rented the company locksmith’s store on the site of the former Levin colliery in Essen-Dellwig and bought the 300 m² hall together with the 2500 m² site the following year. Regular new buildings and acquisitions of the neighboring properties followed. When today’s managing director Jürgen Hengst joined JASTA in 1967 as a commercial apprentice, the company had about a dozen employees, consisting of merchants, technicians and locksmiths.
50 years of JASTA 2009Small economic fluctuations and major economic crises were met by JASTA with the proven virtues of innovative spirit, flexibility and reliability. At times, the company also operated as a contract chipping company. At the same time, the valves have been continuously developed and adapted to new requirements, such as pneumatic and electric actuation. This enabled the company to enter the market as an original equipment manufacturer for the industry.
At the beginning of the 1990s, Heinrich Janssen was able to win Jürgen Hengst, his managing director, as a partner. Plant engineering projects became more complex, and JASTA hired engineers for the first time. Sales representatives and partner companies now also distributed the special butterfly valves in large nominal sizes and for high temperatures beyond European borders.
