Innovation guarantees leading edge

Ever since the company’s early days, it has always been our maxim to constantly improve production
methods and technologies. These endeavours even include developing special production processes
together with technical universities. Thus we are able to maintain and secure our lead, both technologically
and qualitatively.

Valves in industrial use often have to provide reliable service over several decades. This can only be guaranteed
by means of skilful design and high-quality manufacturing. For this reason we have an above-average
range of manufacture and produce practically all of the parts for our valves ourselves. This enables us to have
quality well under control. The following display several important steps in our chain of production.


Welding shop

All welders and processes are TÜV-approved and regularly certified by renowned testing institutions; all work is carried out according to detailed welding plans. Our welding shop uses both manual and semi-automatic welding processes. The most important of these are Submerged Arc Welding (SAW), Tungsten Inert Gas welding (TIG), Metal Active Gas welding (MAG) and electrode manual welding.Equipment for submerged arc welding.

Mechanical processing

Our state-of-the-art CNC machine tools enable us to perform modern 5-axis processing with exact reproducibility.
Special equipment is needed to manufacture the complex sealing design of our products. We develop
and produce this equipment in-house. The above mentioned CNC machine tools enable us to manufacture
individual product elements efficiently and flexibly on-site with a relatively low real net output ratio.

Our department for manufacturing large parts is specially equipped to deal with unusual dimensions.



Prior to delivery our products are all subject to strict approval tests. The tests depend on the intended purpose of use and the accompanying standards and regulations as well as customer-specific guidelines, which are often far stricter than the legally prescribed regulations. Whether classical pressure and leakage tests, function tests under extreme temperature conditions up to –196 °C or +950 °C or tests using specialised media for precisely
determining defined parameters, our extensive testing equipment makes it possible to perform reliable approvals for the requirements of each range of application. These approvals also include simultaneous documentary scrutiny and are exclusively performed under the accompaniment of our quality assurance.


Paint shop

The company has its own paint shop, enabling it to efficiently comply with customers’ wishes regarding surface coating if a particular type of surface protection is required for a certain application. Examples of these are hot zone, drinking water or explosion protection applications.
