Rotary Air Lock Valve
Precision Differential Pressure Feeding and Airlock Sealing
Overview & Engineering Description
Vids Rotary Air Lock Valves (Rotary Feeders) meter dry bulk powders and granules across differential pressure zones while maintaining a pneumatic airtight pressure seal.
Manufactured in precision-machined 3 mm stainless steel 304 with vertex breaker, knocker, and discharge aid to guarantee continuous non-jamming product discharge.
System Advantages
Key Features & Specifications
- Precision machined rotor with tight clearances (0.07 - 0.12 mm) to minimize air leakage
- Open-end or closed-end rotor designs with beveled pocket tips
- Outboard bearings with purgeable air glands for dust isolation
- Drop-through and blow-through housing configurations
- Manufactured in 3 mm SS304 / Cast Iron / Hard Chrome plated
Technical Specification
| Parameter | Standard Specification |
|---|---|
| Rotor Size | 150 mm to 500 mm inlet diameter |
| Pressure Differential | Up to 1.5 bar (g) |
| MOC | SS304 (3mm), Cast Iron, Hastelloy |
| Rotor Pockets | 8-vane or 10-vane scalloped pockets |
How It Works: Working Principle
As the multi-vane rotor turns, top pockets fill with powder from the hopper. The rotating pockets carry the product down to the discharge port, transferring solids while pocket clearances form a labyrinth seal against air pressure.
