We are a family-owned company. That shapes our traditions and the way we think and act. We have been setting standards in the valve industry for over 50 years.

Now and in the future.

Whether they come in the form of knife gate valves, butterfly and check valves or water control gates, isolation valves are our expertise. We combine engineering skills with exceptional manufacturing know-how. Our definition of performance: the highest level of quality, which stands the test of time.

R&D Experiments

Our engineers are constantly working on improving our knife gate valve design and finding solutions for every possible application. Currently, the team is experimenting with different glider systems that are FDA approved and at the same time function perfectly in high-temperature areas of up to 250°C. Six different materials are being tested over a period of 20,000 strokes.
