Pressure reducing valves

Regulating pressure...

We offer a variety of pressure reducing valves for all different kind of media, pressure ranges, flow rates and applications.

Our pressure reducing valves specifically developed for the use with drinking water (type designation with final digit “-6”) are designed for the sanitary area. The valve bodies of these types are made from a special red bronze alloy which is optimally suitable for drinking water; all plastic parts are in conformity with the KTW directives.

The industrial application range of pressure reducers and regulators is far more extensive and versatile than the commonly known applications in the water and compressed air supply. In the industrial area a high flexibility regarding regulating behaviour, flow rate, robustness, media and connection type is essential (our selection guide might be very helpful for you).

All valves shown on this web site are serial standard versions. Nevertheless, we will certainly manage to develop the most qualified valve for your specific needs at a keen and competitive price.
