Quality Without Compromise
At Kugelhahn Müller GmbH, quality isn’t just a standard — it’s a core value that drives everything we do.

The warehouse
Stored in the warehouse are e.g. blanks which are waiting to be processed. Of course, all merchandise is carefully inspected upon arrival.
The warehouse was built in 1999, as the commencement of serial production created the need for more areas which are protected from inclement weather.
Tested valves
This is the section of the warehouse for valves which have already been tested.
High storage capacity allows us to meet the standards defined in the QM handbook with respect to delivery times.
In other words: 100% on-time delivery
delivery time for standard products: less than three days
