With more than fifty years of experience, the UK based Gericke RotaVal is a leading company for these products. As part of the Gericke group of companies, they can combine the expertise from a dedicated rotary valve manufacturer with the global experience from many successfully 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.
