Our broad range of products includes valves, actuators and automation technology.

We are able to offer customized solutions for almost every industrial application. Due to our own production line of actuators and automation technology, the valves can always be equipped with the optimal fitting actuator. This is how an excellent matching of both components is guaranteed, which reduces the energy demand.

Series production is our business – the development of customized solutions for special applications is our passion. When a standard valve does not comply with the requirements, we develop a suitable solution in close cooperation with our customer.

WB / WB 11
Wafe Type Knife Gate valve for water applications.

These valves are all bi-directional and can therefore be installed into pipe systems independent of pressure direction. Full bore and excellent flow characteristics makes them suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.
