What is a Rotary Airlock Valve?

A Vilnesh Rotary Airlock Valve is a compact mechanical device designed to control the discharge of dry powders and granules from storage silos, hoppers, or cyclones while maintaining an airtight seal to prevent air leakage in pneumatic conveying or dust collection systems. Essential for industries such as food processing, pharmaceuticals, chemicals, and agriculture, it ensures precise material flow without compromising system pressure or vacuum. Available in models ranging from 6" to 12" diameter, it is a critical component for efficient and reliable bulk material handling.

How Does a Rotary Airlock Valve Work?

The Vilnesh Rotary Airlock Valve regulates material flow while maintaining system pressure. Here’s a step-by-step explanation of its operation:

  • 01. Material Input: Dry powders or granules are fed into the valve through a top inlet, typically from a silo, hopper, or cyclone.
  • 02. Rotor Movement: A multi-vane rotor, driven by a motor (0.5–3 H.P., 50–60 RPM), rotates within a precision-machined housing, capturing material in the rotor pockets.
  • 03. Material Discharge: As the rotor turns, material is transported from the inlet to the bottom outlet, where it is discharged into downstream equipment like conveyors or mixers.
  • 04. Airtight Seal: Tight clearances between the rotor and housing prevent air leakage, maintaining pressure or vacuum in pneumatic conveying or dust collection systems.
  • 05. Continuous Operation: The valve ensures controlled, continuous discharge without compromising system efficiency.
