A Rotary Valve (also known as Rotary Airlock, Industrial Rotary Feeder, or Discharge Valve) is a critical device for controlled discharge of materials from silos, hoppers, and pipelines. It maintains pressure differentials while transferring powders, granules, and bulk solids across industries like food, pharmaceuticals, mining, and agriculture.

How a Rotary Valve Works

• A rotating chamber with steel blades moves materials in isolated compartments.
• Precise rotor rotation guides materials from inlet to outlet without pressure loss.
• Prevents gas or particle leakage in pressurized or vacuum environments.
• Adjustable rotation speed for accurate material flow control.

Key Applications

• Food Processing: Discharging flour, grains, sugar, and spices from silos.
• Pharmaceuticals: Contamination-free transfer of sensitive powders.
• Mining & Minerals: Handling aggregates, sand, and ores.
• Animal Feed & Agriculture: Transporting feed pellets and fertilizers.
• Chemical Industry: Managing abrasive or hazardous materials with minimal leakage.

Key Advantages

• ✅ Leak-proof design to maintain system pressure and material integrity.
• ✅ Compatible with both positive and negative (vacuum) pressure systems.
• ✅ Durable construction with wear-resistant steel blades and silicone seals.
• ✅ Precise material flow control via motor speed adjustment.
• ✅ Easy integration into pneumatic or mechanical conveying lines.

Maintenance Tips

• Regular lubrication of bearings and shafts.
• Inspect blade edges and sealing gaskets for wear.
• Clean the chamber after handling sticky materials.
• Adjust blade-to-housing clearance to prevent friction.
