About us

Reliability and innovation for more than 50 years!

JASTA-Armaturen was founded by Mr. Janssen in 1959. He started his business with some second-hand machines in a small backyard in Essen. Besides further modified welding throttle valves and casting ring throttle valves, the scope of production included blenders for the heating wholesale business and heating specialists. Even in those days, the factors quality, reliability and innovation made up the basis for the successful and fast expansion of the enterprise.

JASTA won its first industrial customers through the pneumatic and electric automation of own products. Successful developments such as the own double-eccentric shut-off valve Type AB-28/54 set new standards in this field.

As medium-sized company with nearly 50 employees, JASTA has now made the step from the craft enterprise to a renowned and appreciated partner of the industry. Thanks to the development of high-temperatures valves that are capable of coping with temperatures up to 1100°C, we have established our position in the international market and are among the leaders in the field of this technology. Our customers include, among others, companies like Siemens, RWE, Mercedes Benz, MAN Diesel + Turbo, ALSTOM.

The success is still based on the same principles as 50 years ago: Because even today, the name JASTA stands for reliability, quality, and innovation.
