Rotary valves are important components of pneumatic conveying, bulk solids handling, and batching systems. Rotary valves are also known as a rotary airlock, rotary feeder or airlock feeder. The main function of a rotary valve is to control the flow of bulk solids from silo, mixer, cyclone, or hopper under gravity, pressure, and vacuum conditions. Airlocks can work on pressure and vacuum applications.
A wide range of rotary valves are available for different process conditions and physical properties of transferred bulk solids. Abrasive materials, high-temperature powders, food products, big sizes granules can be transferred by selecting proper rotary valve models.
