Product Description
Efficient, Durable & Precise Rotary Airlock Valves
Our Rotary Airlock Valves are engineered to ensure accurate and consistent material flow in industrial processes. Designed for durability and high performance, these valves are ideal for bulk material handling, pneumatic conveying, and dust collection systems.
What is a Rotary Airlock Valve?
A rotary airlock valve is a mechanical device that regulates the flow of bulk solids or powders between two chambers while maintaining an airlock. This allows materials to pass efficiently from hoppers, silos, or feeders into pneumatic conveying systems without causing air leakage or pressure loss.
These valves are critical in maintaining process efficiency, minimizing product loss, and preventing contamination.
Key Features
Consistent Material Flow
Ensures uniform discharge of powders, granules, or bulk solids.

FAQ's of Rotary Airlock Valves:
Q: How does a rotary airlock valve with a 6/8 vane rotor improve material handling efficiency?
A: A 6/8 vane rotor design enhances the valve's ability to seal the airlock chamber and efficiently transfer materials like powder and granules, minimizing air leakage and promoting consistent flow.
Q: What types of industrial processes are best suited for this rotary airlock valve?
A: This valve is ideally suited for processes requiring continuous material transfer, especially those involving powders, dust, or granules in pneumatic conveying or dust collection systems.
Q: When should the rotary airlock valve's lip seal and gland packing be maintained or replaced?
A: Maintenance or replacement of the lip seal and gland packing should be performed regularly, depending on the material processed and operational hours, to ensure optimal sealing and prevent leaks.
Q: Where is flange mounting advantageous in rotary airlock valve installation?
A: Flange mounting is beneficial as it provides a stable and secure attachment to system ducts or hoppers, simplifying installation and maintenance tasks in industrial settings.
Q: What process safeguards are provided by the valve's temperature protection feature?
A: The integrated temperature protection system ensures the valve operates safely by preventing overheating, allowing sustained use up to 120C without risking damage to internal components.
Q: How does the enamel painted finish benefit the rotary airlock valve?
A: The enamel-coated surface guards against corrosion and wear, extending the valve's lifespan and maintaining performance, especially in harsh industrial environments.
