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.

As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the other hand, modulates the mass flow rate. This can be done either on a continuous basis (the feeder

Rotary airlock valve capacity calculations use the following formula: C = R ÷ D ÷ E ÷ S. Fill factor is normally stated at 80% for average conditions but can be adjusted to between 65% and 95% depending on product flowability and pressure differential across the airlock. In general, good flowing products will fill more and sluggish ones less.
