Types of Rotary Airlock Valves in India

If you are looking for the best Rotary Airlock Valves to suit diverse industrial purposes. Our Indian Rotary Airlock Valve Manufacturers in India offer the following types:

  • BAV Rotary Airlock Valves: The BAV Rotary Airlock Valve has been designed specifically to be cleaned and serviced frequently. It can easily have the internal components removed as one tool-less piece by releasing a demountable rotor and rail system. The feature is perfect in sectors like food, pharmaceuticals, and chemicals where hygiene is the key. The BAV reduces operation time and minimizes the costs of the operation since it eradicates rotor gapping, faults of parts, and fast reassembly.
  • Quick-Take-Apart (QTA) Series Rotary Airlock: The QTA Series Rotary Airlock has an easy and frequent dismantlability design, suitable in compact space usage associated areas. Just like the BAV series, except without guide rails; it is ideal in processing facilities where there is not a lot of space available to maintain equipment. The QTA is well suited to the dairy; spice processing or nutraceutical industries and can reduce clean cycles and accelerate product changeovers. It is cast iron or stainless steel constructions up to the expectations of strength and sanitation requirements.
  • Dust Collector Series: Dust Collector Series Rotary Valves are designed for low-pressure, low-temperature dust collection systems. They are ideally suited to mounting under bag houses, cyclones, or hoppers to seal air and dump dust. They are affordable units that offer a basic air seal in place of accurate feed control. With cast iron housings and eight-blade rotors, they are a tough, cost-effective dust management solution for general industrial applications.
  • Heavy-Duty PAV Series: Designed to be strong, the Heavy-Duty PAV Series Rotary Airlock Valves are specifically suited for free-flowing powders, dry, from large hoppers or bins to pneumatic lines. They have pressure differential up to ±15 PSI and are suitable for high-temperature installations up to 500°F or 1,000°F using special kits. Suitable for cement, minerals, and grain applications, they are versatile, highly durable, and dependable in harsh conditions.
  • Abrasion Resistant Rotary Airlock Valves: Built to meet the toughest conditions, the Abrasion Resistant Rotary Airlock Valves come with ceramic-lined housings to accommodate highly abrasive or corrosive materials. They are best for use in mining, foundries, and chemical facilities where normal valves fail prematurely. The honed ceramic lining also provides close tolerances for extended precision and performance. These valves provide highest wear resistance at low maintenance, hence the most durable in the series.
  • Blow-Thru Rotary Airlock Valves: The Blow-Thru Rotary Airlock Valves are specifically designed for direct discharge into pneumatic conveying systems and best suited for materials such as flour, sugar, and plastic pellets. Their vane pockets are larger, and they have up to 50% higher material throughput at lower rotor speeds. This contributes to greater energy efficiency, less wear, and less air leakage. The valves give excellent ROI with reduced operational costs while conveying high performance.
