How to Select a Rotary Airlock
In this application, a 12" airlock at 14 RPM or a 14" airlock at 9 RPM will work. The larger 14" airlock would permit better mass flow of product whereas the 12" airlock might be selected based on economy, smaller height/ footprint, and higher operating speed. Note: For feeding applications, 10-15 RPM typically provides the most uniform ...

Understanding Rotary Valve Design
Housing & End-plates. 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.

What do I really need to know about rotary valve sizing?
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.

Rotary Airlock Valves and How They Work
Rotary airlock valves are also called rotary feeders, rotary valves, or just rotary airlocks. Used in both pressure style and vacuum style pneumatic conveying systems, these valves serve as a "lock" to prevent air loss while simultaneously performing vital material handling functions. Though simple, the rotary airlock valve is a critical …

A rotary airlock capacity is calculated using the fixed volume of the rotary valve cavity (at fill efficiency) and that volume when one full revolution of the blade is made. You then obtain a "volume per revolution" in either ft3/rev or m3/rev to help calculate the capacity in lbs./hr. or kg/hr. Now consider the following calculation:
