The ball sector motor valve type 4030 is used in a range of process engineering processes for shut-off and control tasks, especially with abrasive, pasty and fibrous fluids. This series is characterised by extremely high positioning ratios (300:1) and a high flow rate.

The low-maintenance valves from Schubert & Salzer are used in the chemical, pharmaceutical and food industries, in steel and paper production and also in the manufacture of solar cells. They are particularly characterised by their low energy consumption, long service life and minimal noise pollution.
