The Rotary Valve is a mechanism used as an airlock feeder valve at the bottom of pressurized vessels (both negative & positive) such as dust collectors, cyclones & hoppers. It is used for starch, wood dust & shavings, paper, animal feed and cereals and many other free flowing products.
The housing is fabricated in heavy 10mm thick tube and machined smooth internally. It has an internal rotating rotor with 5 blades positioned in such manner that when the feeder side is open the discharge side is close.
The blades' tip are smooth machined leaving a very minimum clearance between the blade tip and inside of the tube housing. The rotor tube is usually driven by a suitable direct drive in-line reduction gearbox and motor on one end and with a bearing support on the other end.
