Description :

Our highly durable abrasion-resistant rotary airlock valves offer a lasting solution for applications where rotary valves typically wear out due to abrasion. These specialized valves are designed to endure even the harshest abrasive and corrosive environments, outperforming and requiring less maintenance than other rotary valves available in the market.

Our company's Abrasion Resistant Rotary Airlock Valve stands out as the top choice for handling highly abrasive or corrosive products. Its ceramic-lined cast iron housing sets it apart, delivering superior performance compared to airlocks made solely of cast iron, stainless steel, or Ni-hard materials. The thick layers of alumina ceramic coating within the airlock maintain precision tolerances and ensure a prolonged wear life.

Additional features include an oversized mounting flange, heavy-duty outboard bearings, self-adjusting packing glands, and pre-drilled end plates for air purge, enhancing functionality and longevity.

Rotary airlock feeders find various applications in pneumatic conveying systems, dust control equipment, and as volumetric feeders to ensure a consistent material flow throughout processing systems. These feeders serve as crucial airlock transition points, sealing pressurized systems to prevent air or gas loss while facilitating material flow between components with varying pressure levels. Moreover, they act as feeders for accurately metering materials from bins or hoppers into conveying or processing systems at precise flow rates.

Keeping in mind that there are different manufactures and brand names, we will point out the main components of a standard rotary airlock feeder, along with the different end plates, rotors and casings that can be used.
