We stock and supply a full product line of rotary valves. Rotary valves (also known as airlocks, rotary feeders, or airlock feeders) are most often used to 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. It also makes it easier to control the flow of material from bins, hoppers, or silos, onto conveying or processing systems.
A few examples of applications for rotary airlocks include cement, minerals, grains, plastics, flour, gypsum, lime, coffee, cereals, and pharmaceutical manufacturing.
Many options are available including cast iron and stainless steel housings, high temperature ratings, chrome plating, open and closed rotors, tip options, and more.
Here are a few sample drawings for some of our in-stock rotary valves:
