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.Airlocks serve a number of purposes that include acting as a sealing device against loss of air while maintaining a flow of bulk materials between components in a pneumatic conveying system, used as a volumetric feeder for metering materials from bins or silos into a conveying system
