Rotary Airlock Valves

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 component to the efficiency of a conveying system. It’s important to remember that not all rotary valves are necessarily rotary airlock valves – but virtually all rotary airlocks are rotary valves.
