Types of Rotary Air Lock Valve:

Being one of the popular Rotary Airlock valve suppliers in India, we provide these quality valves in different types to suit different requirements of the industries’.

  • Blow-Through Rotary Air Lock Valve: Made from high-grade stainless steel or carbon steel materials, this valve includes components like a rotor, seal, and drive. The rotor spins within the valve body, with blades that pick up materials and pass them through the valve. This allows airflow, making it ideal for various pneumatic transfer tasks.
  • Fall Through Rotary Air Lock Valve: Constructed from materials such as SS, MS, or carbon steel, this valve is designed to handle bulk materials. Its closed end prevents air from escaping, maintaining a consistent flow of materials.
  • Fabricated Rotary Air Lock Valve: As the name suggests, this valve can be fabricated from materials like stainless steel or carbon steel. It is available in customizable options to meet diverse requirements. Its design minimizes air leakage and ensures smooth material flow, making it suitable for handling complex materials at specific temperatures or pressures.
  • Heavy Duty Rotary Air Lock Valve: Constructed from premium materials like cast iron, this valve is built for high-pressure operations. Its robust construction allows for long-term use. With components like the rotor, sealing, and drive mechanisms, it provides consistent performance under heavy loads. It is commonly used for handling abrasive materials or large quantities of materials.

Combined Key Features & Benefits of Rotary Airlock Valves:

We are well-known Rotary Airlock valve suppliers in India and offer it with quality features such as:

  • Material Handling Flexibility: Capable of handling a wide range of materials, including powders, granular materials, and pellets. These are suitable for both dry and wet materials, depending on the valve design and sealing mechanisms.
  • Pressure Differential Control: Rotary airlock valves maintain the required pressure differential between different parts of a system, such as between a silo and a pneumatic conveyor or between dust collection systems and the surrounding environment.
  • Consistent Flow: A rotary airlock valve revolves consistently, allowing continuous movement of materials, in contrast to conventional valves that open and close completely. It is perfect for applications that need a steady feed of material, including dust collection systems or pneumatic conveying systems, owing to its unique asset.
  • Energy Efficient with Less Friction: It operates with smooth and low-friction internal surfaces that can help to reduce energy consumption during working. Its rotating motion, along with engineering, can lower the energy required for the transportation of materials and can reduce wear on mechanical parts.
  • Compact Size with Greater Flow:Although small in size, a rotary airlock valve can handle large amounts of material flow. This size and capacity can be changed as per requirements and make it suitable for situations with compact space. It still provides high performance in this narrow space.
  • Extreme Pressure and Temperature Resistance:Rotary airlock valves are manufactured by our team that can operate them at any kind of temperature and pressure. The different models of this valve can withstand extreme heat and pressure. They are ideal for industries such as foundries or kilns.

Applications of Rotary Air Lock Valve:

We are Rotary Air Lock Valve dealers in India, catering to several renowned industries.

  • Pneumatic Conveying: Rotary airlock valves are commonly used in pneumatic conveying systems to transfer bulk materials like grains, powders, or granules via air pipelines. They add material to the system while minimizing air leakage and maintaining consistent pressure.
  • Construction and Cement: In this field, our offered range of valves are used to manage construction materials. These materials include cement, ash, stones, gypsum, small components, and sands. All these materials can be discharged through the outlet.
  • Dust Collection Systems: Rotary airlock valves are integrated in industrial dust collection systems to release accumulated dust or particulates from cyclones or filters while keeping the surroundings sealed. They stop air from getting out and guarantee the constant elimination of dust, helping maintain clean air and environmental regulation.
  • Petrochemical Industry: Our valves are used in petrochemical processes to handle powder granules or other chemical feedstocks. They bring a regulated supply of materials into reactors or other processing units while avoiding air or gas escaping. This method helps to increase overall production efficiency.

Our rotary airlock valve is produced and processed in compliance with national and international guidelines. Before shipment, the quality control personnel inspect each product, following the necessary quality assurance policies and processes. We, at rotary air lock valve dealers in India, deliver top-notch, trustworthy sales and service.
