Rotary Airlock Valves, also known as rotary feeders, are designed for accurate and continuous discharge of bulk materials from hoppers, silos, cyclones, bag filters, and pneumatic conveying systems while maintaining an effective airlock. The rotating vane rotor delivers uniform material flow and prevents air leakage between pressure zones, improving system efficiency and dust-free operation. These valves are suitable for abrasive and high-temperature applications across cement, clinker, gypsum, fly ash, sinter dust, sponge iron, coal dust, and similar industries. Available in fabricated or cast construction with multiple flange shapes and optional abrasion-resistant linings, they are engineered for long life, reliable sealing, and smooth operation even under demanding conditions.
