Rotary Air Lock Valves

Rotary Air Lock Valves Manufacturer in Pune, India

Rotary Air Lock Valves (RAV) is the Equipment which id fitted below the Bag Filter, Cyclone, Multiclone etc.

The main function of the RAV is to lock the air and discharge the dust /powder.ln the bag filter system there is negative pressure in the bag filter. So at the powder discharge point if there is any air leakage the powder will not fall down. So to restrict the sir leakage we provide the rotary a, lock valve. RAV consists of a stator & rotor. The radial $ axial clearance between is 0.1 to 0.3mrn. The rotor has vanes (6 or 8) welded on the shaft. The rotor is mounted on the bearings at both the ends of the stator. A geared motor is provided to rotate the rotor. Since the clearance between rotor.

Working Principle of Rotary Air Lock Valves

A Rotary Air Lock Valves (RAV) works by sealing air while continuously Discharging Dust or Powder from Bag Filters, Cyclones, and Multiclones. The Valve consists of a Rotor with 6 or 8 Vanes Mounted inside a stator, maintaining a precise 0.1–0.3mm clearance to prevent air leakage. A geared motor rotates the rotor, moving material through in controlled pockets without disturbing the negative pressure inside the filter system — ensuring continuous, efficient discharge and consistent dust-handling performance.

Applications of Rotary Air Lock Valves

Bag Filter Systems: Continuous dust discharge without air leakage
Cyclone Separators : Powder discharge under negative Pressure conditions
Multiclone Dust Collectors: Efficient material handling in high-dust environments
Pneumatic Conveying Systems: Airlock control between conveying lines
Powder Processing Plants: Controlled Material Flow during Production

Why Choose Rotary Air Lock Valves

A Rotary Air Lock Valves prevents air leakage while continuously discharging dust or powder from filtration systems.

Precise Air Sealing – 0.1–0.3mm rotor-stator clearance minimizes leakage
Reliable Continuous Discharge – Consistent performance under negative pressure
Durable Rotor Design – 6/8-vane construction for long service life
Low Maintenance – Reduces downtime in Dust Collection Systems
