A Rotary Airlock Valve is a mechanical device used to control the flow of bulk materials between different components of a system while maintaining an airtight seal. It is commonly used in various industries, including food processing, pharmaceuticals, chemicals, plastics, and more. : The bulk material to be transported is fed into the inlet of the rotary valve. This can be done manually or through an automated feeding system. Rotary Airlock Valve is commonly used in applications where there is a need to control the flow of bulk materials between different pressure zones or to feed materials into a pneumatic conveying system. They are especially useful when handling powders, granules, pellets, and other similar materials.
