Round rotary valve

The use of rotary valves is a critical component for many dust collection processes. Rotary valves make it easier to control the flow of material from bins, hoppers, or silos, onto conveying or processing systems.

Rotary valves (also known as airlocks, rotary feeders, or airlock feeders) transition material from one pressurized point, such as a dust collector, to another unpressurized point, such as a drum or bin. The valve seals a pressurized system against loss of air and pressure. Rotary Valves help ensure loss of product during processing is minimized.

Typical dust collection applications for rotary airlocks are dust collection, pneumatic conveying, pollution control, mixing, feeding, weighing, drying, and blending. Some of the relevant industries for rotary airlocks include metalworking, cement, minerals, agriculture, wood, paper, rubber, textiles, grains, paint, pharmaceutical manufacturing, and many more.
