The Differences Between a Rotary Valve, Rotary Airlock, Rotary Feeder, and a Rotary Airlock Feeder

A rotary valve is a valve without a home, at least until you determine the application and accessories, which can make it either an airlock, feeder, or both. The following explains the different ways a rotary valve can be used…

 

 

 

Rotary Airlock

A rotary valve is a valve without a home, at least until you determine the application and accessories, which can make it either an airlock, feeder, or both. The following explains the different ways a rotary valve can be used…

Rotary Feeder

A Feeder is a valve or device that’s main purpose is metering material into or out of something but is not separating a pressure differential. These can be volumetric feeders, vibratory feeders, screw conveyors, OR a Rotary Feeder.

Rotary Airlock Feeder

A Rotary Airlock Feeder does BOTH, it separates a pressure differential while allowing material to pass through. Imagine a revolving door into a building; it allows material (people) to pass through while maintaining the pressure differential between the building and outside. Rotary airlock feeders are designed to leak air and sacrifice accuracy of metering, BUT… function as both an Airlock and a Feeder simultaneously.
