Wear-protected rotary valves and diverter valves

Wear-protected rotary valves and diverter valves are distinguished by their reliability of operation, long service life and hence minimal repair and maintenance requirements. Consequently, these products are ideal for use in the mineral industry. In the cement industry, for example, one of the advantages of rotary valves in comparison to the more conventional screw pumps lies in the considerable saving in energy. Power requirements are reduced by more than 90% compared to systems equipped with screw pumps. Furthermore wear-protected rotary valves provide a longer operating life by up to 50%. A further decisive advantage is the negligible time/cost of converting a system for use with rotary valves.  As rotary valves are relatively small in comparison to conventional systems, there are no space requirement problems to contend with. Rounding off the product range are ATEX-certified versions (against explosion transfer) and high-temperature versions for the safe and reliable handling of hot materials up to 500 °C.
