How to Select a Rotary Airlock/Feeder Valve for Your Powder Processing
For most valves under 16" in flange size this is in the 25-30 rpm range. So, for this application C=100/35/0.7/25 or 0.163 cu. ft./revolution. You should select a valve with a swept volume at least this large and run the rotor at a speed that will meet the required convey rate. Flange size.

How to Choose Between a Drop-Through vs. Blow-Through Rotary Valve
A drop-through design may be your best option when there are a number of rotary valves in series on a single convey line. In this circumstance, a blow-through design could put too much resistance on the product and cause it to break down, while the obstruction-free convey transition under a drop-through design may better protect the …

What is a Rotary Valve? Where is it Used and With Which
A rotary valve is simply a mechanical device used for the continuous discharge of bulk solid materials. The term 'rotary' is derived from the valve's operating principle. During bulk material handling, the valve's vanes rotate to produce a successful operation, hence, the term 'rotary'. The valve is an essential component in the ...

Fixing common rotary airlock valve problems
No rotary airlock valve is 100 percent leak-proof. Because of how the valve is constructed, some clearance must be left between the rotor and the housing and headplates. Although each valve manufacturer has individual clearance standards, typical blade-to-housing and blade-to-headplate clearances are between 0.003 and 0.012 inch.

Understanding Rotary Valve Design
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.
