What Is a Rotary Airlock Valve? - Featured image

A rotary airlock valve is a mechanical device used in bulk material handling

systems to transfer powders, pellets, or granules while maintaining pressure

isolation between two sections of a process. It is commonly installed in

pneumatic conveying systems.

The valve works using a rotating rotor with multiple blades inside a housing. As

the rotor turns, it creates small pockets that carry material from the inlet to the

outlet while preventing air from escaping.

A rotary airlock valve is widely used in industries such as cement manufacturing,

food processing, and chemical production to ensure controlled material flow and

efficient system performance.
