What is a Rotary Airlock Valve and Why It is Important?
Rotary Airlock Valve is a mechanical device consisting of a rotating rotor with multiple pockets or vanes enclosed within a precisely machined housing. As the rotor turns, material enters the pockets from the upper inlet, is carried through the valve and is discharged from the lower outlet.
What is the Purpose of a Rotary Airlock Valve?
Rotary Airlock Valve controls the discharge of bulk material while maintaining pressure differences. It allows material to pass between equipment without significant air or gas leakage. It is widely used in dust collection, pneumatic conveying, and material handling systems.
How Does Rotary Airlock Valve Work?
Being a leading Rotary Airlock valve manufacturers in Hyderabad, We have mention the process of it such as:
Material Entry: Bulk material enters the valve through the inlet from a hopper, silo, cyclone, bag filter or other process equipment.
Rotor Pocket Filling: As the rotor rotates, its pockets or compartments receive a controlled quantity of material.
Airlock Action: The filled pockets move through the housing while the rotor and housing clearance helps limit unwanted air movement between the inlet and outlet zones.
Material Transfer: The rotating pockets carry the material toward the discharge side without requiring a separate manual discharge operation.
Controlled Discharge: When the pockets reach the outlet, gravity or downstream conveying conditions allow the material to leave the valve.
Continuous Rotation: The rotor continues rotating to repeat the filling, transfer and discharge cycle for continuous material handling.
Speed Control: Where required, a suitable geared drive and VFD arrangement can be used to adjust rotor speed according to the required feeding or discharge rate.
