Rotary Air Lock Valve

A Rotary Airlock Valve is, also known as a rotary valve or rotary feeder, is a mechanical device commonly used in bulk material handling systems to control the flow of granular or powdered materials between two separate environments with differing pressures or atmospheres. Rotary Air Lock Valve ensures to achieve controlled transfer of materials while maintaining an airtight seal, preventing air leakage and maintaining the pressure differentials between the two connected systems.

• Rotor: The rotor is the central rotating element of the valve. It typically consists of vanes or blades that sweep across the valve's inlet and outlet openings. The rotor's rotation allows it to maintain a continuous flow of material while preventing direct airflow between the connected systems.


• Housing: The housing contains the rotor and creates the chambers for material transfer. It features inlet and outlet ports and is designed to maintain an airtight seal to prevent air leakage during operation.


• Seals: Sealing components, such as packing glands or mechanical seals, are used to maintain an airtight seal between the rotor and the housing. These seals prevent air or gas leakage and ensure that the pressure differential between the two connected systems is maintained.


• Drive Mechanism: The rotary airlock valve is powered by a drive mechanism, often an electric motor or gear motor, that rotates the rotor. The speed of rotation can be adjusted to control the rate of material flow.

• Material Inlet: Material enters the rotary airlock valve through its inlet port, usually from a hopper or a conveyor system.


• Rotor Rotation: The rotor rotates within the housing, and its vanes sweep the material from the inlet side to the outlet side. The rotation of the rotor creates discrete chambers, preventing direct airflow between the inlet and outlet.


• Material Discharge: As the rotor rotates, the material is deposited into the outlet port. The outlet can be connected to various downstream equipment, such as pneumatic conveying systems, bins, silos, or other processing units..

• Pneumatic Conveying Systems: Rotary airlock valves are often used in pneumatic conveying systems to maintain an airtight seal between different pressure zones while allowing a controlled flow of materials.


• Dust Collection Systems: In dust collection systems, rotary airlock valves are used to discharge dust or other particulate matter from dust collectors or cyclone separators.


• Bulk Material Handling: These valves are utilized to regulate the flow of bulk materials in various industries, including agriculture, food processing, plastics, chemicals, and minerals.


• Industrial Processes: Rotary airlock valves are integrated into industrial processes that involve controlled material transfer between different processing stages or equipment.


• Energy and Environmental Applications: They can be used in energy production systems, such as biomass combustion and thermal processes, as well as in environmental applications to control emissions.
