About us

No matter the industry and always adaptable. On this basis we have developed ourselves to a technological leader in butterfly and shut-off valves. Recently we have expanded our product range with innovative measurement and control technology.

We have stayed true to our roots: we still produce at the same site in Essen, Germany where Heinrich Janssen founded the company in 1959 – with constantly increased capacity.

Old values with new concepts

Today we operate side by side with traditional values and contemporary concepts in a modern middle sized company. We implement planning certainty throughout the whole project cycle with certified workflows and progressive project management.
In this, experienced and young employees act jointly and practice a culture of openness and mutual respect. nnovations cannot be demanded, we challenge them with a flat hierarchy and short decision channels.

Interdisciplinary and multicultural: in our company we lay value on variety. Because we produce valves for different application in the whole world, we like to draw from a great pool of qualifications, experience and ideas.

We offer a variety of construction and production services under one roof. In this we profit from short lines of communication, because construction and production are all on the same site in Essen. This strategy guarantees complete control over all processes and maximum quality assurance.
