Air Lock Rotary Valve

PRODUCT DESCRIPTION

Air Lock Rotary Valve

An Air Lock Rotary Valve, also known as a rotary feeder or rotary airlock, is a mechanical device used to regulate the flow of bulk materials between different areas with varying pressure or environmental conditions. 

These valves function as airlocks, preventing air leakage while facilitating the continuous and uniform transfer of materials.

In industrial processes that involve the handling of bulk materials, efficient and reliable material transfer is essential. Air Lock Rotary Valves have emerged as indispensable components for controlling the flow of powders, granules, and other materials while maintaining an airtight seal. This article delves into the functionalities, benefits, applications, and innovations of Air Lock Rotary Valves in streamlining material handling for various industries.

Air Lock Rotary Valve Features :

Air Lock Rotary Valves offer several advantages in material handling processes:
  • Airtight Sealing
  • Material Flow Control
  • Compatibility with Various Materials
  • Minimized Material Loss
  • Air Lock Rotary Valve Application :

    Air Lock Rotary Valves find versatile applications in numerous industries:
  • Pneumatic Conveying Systems
  • Dust Collection Systems
  • Mixing and Blending
  • Feeding and Metering
  • Types of Air Lock Rotary Valves :

    There are different types of Air Lock Rotary Valves, each designed to accommodate specific materials and applications:

    1. Drop-through Rotary Valves :
      These valves are suitable for free-flowing materials and are commonly used in gravity-fed systems.
    2. Blow-through Rotary Valves :
      Blow-through valves are ideal for pneumatic conveying systems, handling materials that are more difficult to convey.
    3. Side-entry Rotary Valves :
      Side-entry valves are utilized in applications where the valve’s inlet and outlet are on the same plane, facilitating horizontal material transfer.
    4. Abrasion-resistant Rotary Valves :
      For handling abrasive materials, abrasion-resistant valves with special coatings or construction materials are used to prolong valve life.

    Working Principle :

    The operation of an Air Lock Rotary Valve involves the following key steps:

    Step 1 : Material Inlet: Bulk materials enter the valve from a hopper or a source through an inlet port.

    Step 2 : Material Discharge: As the valve rotates, pockets or cavities within the valve’s rotor carry the material from the inlet to the outlet side.

    Step 3 : Sealing: During the rotation, the valve’s housing maintains an airtight seal between the inlet and outlet sides, preventing air leakage and maintaining pressure differentials.

    Step 4 : Material Discharge: The material is discharged through the outlet port, either into a downstream process or a conveying system.

    Step 5 : Continuous Operation: The rotary valve’s continuous rotation ensures a steady flow of material without interruptions, making it suitable for various material handling applications.
