Rotary Airlock Valve

Rotary airlock valve, also called rotary feeder or star feeder, is a critical sealing and discharging accessory for dust collectors, silos and conveying systems. It rotates the impeller inside closed housing to continuously discharge bulk powder and granular materials while maintaining airtight isolation between upper and lower pressure chambers.

Main Types

Cast Iron Rotary Valve: Standard type for common dry dust, low cost and wear-resistant.

Stainless Steel Rotary Valve: Food-grade & anti-corrosion, for food, chemical and corrosive materials.

Blow-through Airlock Valve: Matched with pneumatic conveying pipeline for high-pressure feeding.

Key Advantages

Excellent air locking effect to avoid air backflow and gas leakage.

Uniform continuous discharging, stable feeding flow.

Compact structure, easy installation and low maintenance cost.

Customizable size, drive mode and rotor clearance as working conditions.

Application

Supporting filter cartridge dust collectors, cyclones, screw conveyors, bucket elevators, widely used in cement, grain, feed, chemical, metallurgy and environmental protection industries.
