Standard Rotary Airlock Valve

ALIS Valves offers Standard Rotary Airlock Valves for industrial applications requiring controlled discharge and consistent feeding of bulk solid materials. These valves feature a rotating rotor with multiple pockets that carry material from the inlet to the outlet as the rotor turns. The close-clearance design helps regulate material flow while limiting air leakage between connected equipment, making the valve suitable for compatible dust collection, hopper discharge and pneumatic conveying systems. Depending on the application, the rotor and housing can be selected to handle different types of powders, granules and dry bulk materials.

Standard Rotary Airlock Valves are suitable for applications in cement plants, power generation facilities, food processing industries, chemical plants, mining operations and bulk material handling systems. They are commonly installed beneath silos, hoppers, dust collectors, cyclones and bag filters to control material discharge into downstream equipment. Important selection factors include material characteristics, particle size, bulk density, required discharge capacity, operating temperature, pressure differential, rotor configuration, body material, sealing clearance and drive requirements. Selecting the appropriate Standard Rotary Airlock Valve helps support consistent material feeding, controlled discharge and reliable operation under the intended working conditions.
