Airlock Rotary Valve

Product Description
Our Airlock Rotary Valve is a precision-engineered device designed for controlled discharge and feeding of dry bulk materials from hoppers, cyclones, silos, or dust-collection systems. It maintains an air seal while allowing continuous material flow, ensuring efficient pneumatic conveying and dust-tight operation.

Key Features

• Robust Construction: Heavy-duty cast iron / stainless steel housing for long service life.

• Smooth Operation: Precisely machined rotor and housing minimize air leakage.

• Custom Sizes: Available in various diameters and capacities to suit specific process requirements.

• Drive Options: Direct drive or chain drive with geared motor.

• Material Versatility: Handles powders, granules, pellets, cement, fly ash, grains, chemicals, and more.

• Temperature Range: Suitable for standard or high-temperature applications.

Typical Applications

• Cement plants

• Food and grain processing

• Chemical and pharmaceutical industries

• Dust collection systems

• Pneumatic conveying systems

Specifications (Typical)

• Rotor: 6/8 vane fabricated or cast

• Capacity: 50 kg/hr to 10 TPH (customizable)

• Pressure: Up to 1 bar differential

• Finish: Painted / Powder-coated / SS 304 / SS 316

Benefits

• Maintains consistent feed rate

• Prevents air leakage and product loss

• Reduces dust emissions and energy consumption

Our Industrial Rotary Airlock Valve is a precision-engineered feeder and isolation device designed to maintain pressure differentials while enabling controlled discharge or feeding of bulk materials. It’s ideal for pneumatic conveying systems, dust collection, hoppers/silos, cyclones, bag filters, and similar industrial applications.

Key Features

• Airlock Sealing: Close clearance between rotor tips and housing (0.1–0.5 mm or per requirement) helps to minimize air leakage and maintain pneumatic integrity.

• Rotor Design: Multi-vane rotor (4, 6, 8, 10, or custom) with either fixed or adjustable/replaceable tips.

• Robust Construction: Body materials such as cast iron, mild steel, stainless steel (SS304, SS316), or special alloys for corrosive or hygienic environments. Chrome‐plated or hard-faced parts for abrasion resistance.

• Drive Mechanism: Electric motor + gear reducer; options for direct coupling, chain drive or VFD (Variable Frequency Drive) for adjustable rotor speed.

• Temperature & Pressure Handling: Designed to withstand differential pressures (vacuum/positive pressure systems) and moderate to high temperatures, depending on materials used.

• Hygienic & Cleanability Options: Quick-clean / sanitary designs, polished surfaces, easy disassembly, optional purge ports, etc., especially useful for food, pharma, and chemical industries.

• Customizations Available: Size (diameter / nominal bore), number of vanes, material finish, drive power, rotor tip style, flange types (round/square), operating speed, etc.

A Rotary Airlock Feeder separates a pressure differential while allowing material to pass through it. Best way of thinking of how it works is imaging a revolving door in a building; it allows material to pass through, but maintains the pressure differential between the building and outside.
