Rotary valves are a proven equipment to discharge and convey bulk solids, to isolate pressure differentials; they are also used as flame barrier or explosion propagation isolation in ATEX zones. As part of the Gericke group of companies, Gericke RotaVal has combined its industry knowledge as a rotary valve manufacturer with the experience from various supplied powder processing and bulk handling installations.
Rotary valves are found in many pneumatic conveying systems. They can also act as a safety device to isolate different process steps (airlock, flame barriers, explosion propagation valve). Another application is metering, for example when filling FIBCs.
The design and manufacturing of rotary valves beyond the commonly used size ask for specific knowledge and large machining centers. Large rotary valves are used for large throughputs or for handling of large size and lumpy particles, for example in the petrochemical, chemical and aggregates industries.
With in-house development and production Gericke RotaVal has a large experience of building valves up to sizes of 600 by 1200 mm, often with special coatings.
