Rotary Air-lock Valves are used at the bottom of Bins, Cyclones, Dust Collectors or Feed Hoppers to discharge materials at a controlled rate or act as an Airlock. They are also used to introduce materials into positive or negative conveying systems. A Rotary Feeder / Airlock Valve consists of a rotor which turns at a

Rotary valves are made up of 4 main parts; cylinder (or housing), end-plates, rotor, and drive package. Magnum Systems' rotary valves are made from cast gray iron, stainless steel and or Hard Chrome. The reason the housings are made out of a cast mold is the strength it adds to the design that is not possible if just fabricated.

The size refers to the diameter of the valve's opening, usually called the flange or inlet. If we get multiple results for the valve size, we generally pick the smaller option. In some cases, like with abrasive material, we recommend upsizing the rotary valve in order to lower the RPM and gain more volume per rotation.

A Rotary Airlock Valve, an essential component in bulk material handling systems, facilitates controlled feed while maintaining an airtight seal. This instrument's main role lies in regulating the flow of solid bulk materials from one chamber to another while ensuring minimal air leakage, thus maintaining pressure and process integrity.

For a pneumatic conveying system, a minimum air conveying velocity must be maintained (typically 3500 FPM). If this drops below, the pipeline may block. A positive displacement blower is a constant flow air mover that will always maintain constant air velocity in the pipe against various discharge pressures, which helps prevent blockages.

Air leakage: Air leakage is a common phenomenon in rotary airlock valves. In fact, manufacturers design these valves for around 0.0003 to 0.012-inch leakage clearance. Therefore, an air leak is inevitable in rotary valves. However, if the air leakage surpasses calculated or theoretical air leakage, then it's a problem.
