In the water and sewage industry high pressure hydraulics is often used to operate large valves and hydraulic shutters requiring a high degree of driving force and safety. This poses special requirements for the hydraulic components used. Biodegradable material demands special care with regards to sealing agents. For these components a high degree of leakage safety is required to meet regulations for water pollution controls. Working with sewage our products are often exposed to aggressive matters necessitating a special anti-corrosion coating treatment. Moreover explosive gases may occur in these areas so special care has to be taken to avoid sparking ignition.

To get a definite switching status we rely on a variety of sensory options. Proximity switches (partly in ATEX), stoke measuring systems or internal terminal position recognition are employed upon customer request.
