Rotary Air
Lock Valve
Rotary Air Lock Valve Manufacturer in India
RK Engineering is a reliable Rotary Air Lock Valve Manufacturer in India, manufacturing heavy-duty rotary airlock valves and rotary feeders for controlled handling of powders, granules and bulk solid materials. Our valves are designed for pneumatic conveying, dust collection, cyclone separation and material handling systems.
A Rotary Air Lock Valve helps regulate material flow while maintaining a pressure seal between two different pressure zones. This makes it an important component in bag filters, cyclones, spray dryers, pneumatic conveying lines and dust collection plants.
What Is a Rotary Air Lock Valve?
A Rotary Air Lock Valve, also known as a Rotary Feeder, is an industrial material-handling device designed to regulate the discharge of powders, granules and bulk solids while maintaining an air or pressure seal.
The valve consists of a rotating rotor fitted inside a precision housing. Material enters through the inlet and fills the rotor pockets. As the rotor turns, the material is transferred toward the discharge side in a controlled and continuous manner.
The close clearance between the rotor and housing helps minimize air leakage and pressure loss, making rotary airlock valves suitable for pneumatic conveying systems and dust collection equipment.
How Does a Rotary Air Lock Valve Work?
A rotary airlock valve transfers bulk material through rotating rotor pockets while helping maintain pressure separation between connected processing equipment.
Material Entry
Powder, granules or other suitable bulk material enters the valve through the top inlet.
Rotor Filling
Material fills the pockets located between the rotor blades inside the valve housing.
Controlled Rotation
The rotor rotates at a controlled speed and transfers the material toward the discharge outlet.
Material Discharge
Material leaves the rotor pockets while the valve helps maintain separation between pressure zones.

Industrial Rotary Air Lock Valve for Pneumatic Conveying
An industrial Rotary Air Lock Valve is a key component in pneumatic conveying systems where dry bulk material must be transferred between areas operating at different pressure levels.
The rotating rotor meters material into the conveying line while the close clearance between rotor and housing helps reduce pressure loss and unwanted air leakage.
RK Engineering manufactures Rotary Air Lock Valves in Ahmedabad, Gujarat for customers requiring reliable powder feeding, dust discharge and bulk-solid handling equipment.
Rotary Air Lock Valve for Dust Collector
A Rotary Air Lock Valve for dust collector is typically installed below the collection hopper. Dust falls into the rotor pockets and is discharged continuously while the valve helps isolate the pressure inside the dust collection system.
This configuration supports continuous operation and reduces the need to stop the dust collector for routine material discharge. Rotary airlock valves can also be used beneath bag filters and cyclone separators.
Rotary Feeder for Powder and Bulk Material Handling
A Rotary Feeder provides controlled volumetric movement of suitable powders and granular materials. The rotor pockets transfer a defined amount of material during each revolution, helping regulate the downstream feed rate.
The correct rotor arrangement depends on bulk density, particle size, abrasiveness, temperature, moisture, flow characteristics and required material handling capacity.
Rotary Air Lock Valve FAQs
A Rotary Air Lock Valve is a material-handling device used to regulate the discharge of powders, granules and bulk solids while helping maintain a pressure seal between different parts of a processing system.
Material enters rotor pockets through the inlet. As the rotor turns, the material is transferred toward the outlet and discharged while the rotor and housing help limit airflow between pressure zones.
The terms Rotary Air Lock Valve and Rotary Feeder are often used for similar rotary devices. A rotary airlock primarily emphasizes pressure sealing, while rotary feeder applications may emphasize controlled material feeding.
