Innovations in the field of dry materials handling operations
The extensive range of available valve types reflects the challenges of controlling, directing, and metering the flow of dry bulk materials in processing operations. Not all valves control the flow by gravity of materials from storage vessels or through mechanical conveying systems; many are used to direct the flow through pneumatic conveying systems.

Others are used in dense phase pneumatic conveying systems to release pressurized materials from the blow pots that provide the motive power.
