Rotary Air Lock Valve
Rotary Air Lock Valve
The VIRA Engineering Rotary Airlock Valve is a precision-engineered feeder designed to control the flow of bulk solid materials between two different pressure zones while maintaining an efficient airlock seal.
It combines the functions of feeding, metering, and sealing, ensuring smooth handling of dry, free-flowing powders, granules, crystals, or pellets. The valve features an impeller mounted directly on the gearbox shaft with specially designed inlet ports that create a scissor-cutting action for smooth operation, minimizing wear and extending equipment life.
Advantages
- Maintains optimal airlock between pressure differentials
- Prevents product leakage and contamination
- Longer bearing & impeller life due to cutting-edge design
- Handles abrasive, sticky & fine powders efficiently
- Continuous, uniform material feeding
