Rotary Air Lock Valve

Rotary Airlock Valves Are A Type Of Rotary Feeder And Are Often Referred To Simply As A Rotary Airlock Or Rotary Valve. They Provide Feeding And Metering Functionality Of A Standard Rotary Feeder But Their Primary Duty Is To Maintain Pressure And Provide An Optimal Airlock Seal Between Different Product Conveying Transitions, Such As Gravity To Pneumatic Conveying Lines.

The Design Includes An Impeller Which Is Mounted Directly Onto The Gearbox Shaft And An End Plate Mounted Bearing With Lip Seals On The Non-Driven Side. The Inlet Ports Have VS Cast Into The Side Wall To Create A Scissor Cutting Action Between Impeller Blade And Casing. This Ensures Smooth Rotation Without The Chopping Effect Experienced With Other Valves. The Result Is Increased Bearing And Impeller Tip Life.

Rotary Airlock Feeders Have Wide Application In Industry Wherever Dry Free-Flowing Powders, Granules, Crystals, Or Pellets Are Used. Typical Materials Include: Cement, Ore, Sugar, Minerals, Grains, Plastics, Dust, Fly Ash, Flour, Gypsum, Lime, Coffee, Cereals, Pharmaceuticals, Etc
