Rotary airlock valves are also called rotary feeders, rotary valves, or just rotary airlocks. Used in both pressure style and vacuum style pneumatic conveying systems, these valves serve as a "lock" to prevent air loss while simultaneously performing vital material handling functions. Though simple, the rotary airlock valve is a critical …
