With the range of discharge valves type ZRD and blow-through valves type ZXD, Coperion GmbH now offers the food industry the first rotary valves in the world in Hygienic PLUS execution to be certified in compliance with the criteria of the European Hygienic Engineering & Design Group (EHEDG), type ED.
These criteria formulate the requirements to be met by components that are used in systems with dry operation and dry cleaning processes. Important features of the certified Hygienic PLUS rotary valves are that they are easy to dismantle and that the component areas can be easily accessed for cleaning and inspection. The surfaces are smooth and the interfaces to the areas in contact with the product are step-free. Coperion was already a pioneer years ago in the development of CIP-compliant (Cleaning in Place), certified rotary valves and diverter valves that are cleaned with liquids. With the new EHEDG type ED-certified rotary valves the company now also supplies dry cleaning components to assist system integrators and end users who must fulfill requirements when it comes to sanitary design and operational safety in the food industry during the production, processing and transport of powders and pellets. The ZRD and ZXD Hygienic PLUS rotary valves are used in pneumatic conveying systems and for the discharge of powdered and pelletized materials.
