Introduction

Searching for a dependable Rotary Airlock Valve for dust collection, pneumatic conveying, or hopper discharge? Siddhi Vinayak Engineering designs robust rotary valves that meter bulk solids while maintaining an air seal between zones of differing pressure—minimizing air leakage, protecting system efficiency, and ensuring consistent product flow.


Description

A Rotary Airlock Valve (also called a rotary feeder) uses a bladed rotor turning within a close-clearance housing to discharge powders or granules at a controlled rate. Our valves are available in drop-through and blow-through configurations with options for cast iron, MS, or stainless steel wetted parts, various rotor styles (open, closed, scalloped), and food-grade or abrasion-resistant seals. Precision machining, tight tip clearances, and balanced rotors deliver low leakage and long service life.


Applications and Benefits

Applications Benefits
  • Dust collector hopper discharge for bag filters and cyclones
  • Pneumatic conveying systems (dilute & dense phase) as a feeder/airlock
  • Silo & bin bottom discharge for powders, crystals, and pellets
  • Process dosing for mills, dryers, mixers, and reactors
  • Food, pharma, chemical and mineral processing plants
  • Maintains pressure differential with minimal air leakage
  • Uniform metering; reduces surging and rat-holing
  • Heavy-duty build with wear options for abrasive duty
  • Hygienic designs with easy-clean access for quick changeovers
  • Customizable drives, speeds, and interlocks for safe operation

Key Features of Rotary Airlock Valves

  • Drop-through & blow-through constructions with flanged inlet/outlet
  • Rotor options: open/closed vanes, shrouded ends, adjustable tips
  • Tight radial & axial clearances for low leakage and high volumetric efficiency
  • Materials: CI, MS, SS304/SS316; hardfacing for abrasive products
  • Seal choices: stuffing box, lip seals, air purge, or mechanical seals
  • Direct-coupled geared motor or chain drive with VFD speed control
  • Quick-release end covers for inspection and sanitation
  • Optional explosion vents/ATEX-ready components for dust safety

Where Rotary Airlock Valves Are Used

  • Dust Collection: Discharging captured dust from bag filters, cyclones, and scrubbers without false air ingress
  • Pneumatic Conveying: Feeding powders into conveying lines while preserving conveying pressure
  • Storage & Batching: Controlled discharge from silos, bins, and day hoppers to downstream processes

Why Choose Us?

With 12+ years of bulk-solids handling expertise, Siddhi Vinayak Engineering delivers airlocks engineered for your product characteristics—bulk density, particle size, abrasiveness, and temperature. We support selection, interlocking, and commissioning so your system starts up smoothly and stays reliable.


Uses & Importance

Rotary airlocks are critical to system performance: they prevent air short-circuiting, stabilize conveying velocities, and protect filters from re-entrainment. Correctly sized valves reduce energy loss, improve product recovery, and extend bag/filter life—saving maintenance time and operating cost.

FAQs

1. How do I size a Rotary Airlock Valve?
Sizing depends on required throughput (m³/hr), bulk density, rotor speed, and number of vanes. We calculate volumetric capacity and select clearances to meet leakage limits.
2. What is the difference between drop-through and blow-through?
Drop-through mounts under a hopper and discharges by gravity; blow-through integrates the conveying line into the end covers for compact feeding directly into the pipeline.
3. Which seal is best for my application?
For general duty, stuffing boxes work well; for hygiene or pressure, use lip/mechanical seals. Air purge adds protection against dust ingress and heat.
4. Can I handle abrasive or hot products?
Yes. We offer hardfaced tips, wear liners, and high-temperature bearings/seals for abrasive or high-temp service.

Conclusion

Choose Siddhi Vinayak Engineering for engineered Rotary Airlock Valves that keep your system sealed, efficient, and easy to maintain—backed by application support and lifecycle service.
