Rotary Airlock Valve

A: The correct model depends on material type, conveying capacity, system pressure, temperature, and sealing requirements. Different working conditions require different structures and materials. It is recommended to provide detailed operating parameters for professional selection support.

A: Yes. Customized solutions are available based on different application requirements. We can customize dimensions, rotor structures, material configurations, drive methods, flange connections, and sealing systems. Special optimization is also available for food, chemical, lithium battery, and explosion-proof applications.

A: The price is mainly affected by valve size, material selection, structural configuration, sealing requirements, and customization level. Stainless steel materials, explosion-proof designs, wear-resistant treatments, and high air-tightness structures usually increase overall cost. Operating conditions and industry standards may also influence the final quotation.

A: Yes. We provide selection guidance, installation support, technical consultation, and after-sales service. Spare parts supply and maintenance recommendations are also available. For export projects, remote technical assistance can be provided to support installation and operation.

A: A rotary airlock valve is mainly used for continuous discharge and air sealing in pneumatic conveying systems. It helps maintain stable system pressure while ensuring uniform material feeding, reducing air leakage, and improving conveying efficiency.

A: Material flowability, abrasiveness, adhesion, and particle size directly affect equipment structure and material selection. Abrasive materials require wear-resistant designs, sticky materials may need anti-blocking structures, and food or pharmaceutical industries often require stainless steel construction.

A: Yes. For high-temperature, high-pressure, or other demanding industrial conditions, high-temperature materials, reinforced valve bodies, and advanced sealing solutions can be provided according to specific operating requirements.

A: Improving sealing performance usually involves optimizing rotor-to-housing clearance, sealing structures, machining precision, and rotational speed control. For applications requiring higher air tightness, special sealing systems and precision-machined structures can be used to minimize air leakage.

A: Please provide material type, conveying capacity, operating temperature, system pressure, industry application, and installation requirements. Hanye’s engineering team will recommend suitable products and provide technical solutions and quotation support based on your working conditions.

A: A rotary airlock valve is a key feeding and air-sealing device used in pneumatic conveying systems, dust collection systems, batching lines and bulk material handling processes. It allows powders, granules or pellets to discharge continuously from one process stage to another while reducing air leakage and maintaining pressure balance inside the system.

In industrial powder handling applications, a rotary airlock valve is commonly installed under silos, hoppers, bag filters, cyclones, dust collectors, mixers or conveying pipelines. By rotating a precision-machined rotor inside the valve body, the equipment transfers material at a controlled rate while helping isolate pressure between the upper and lower equipment.

HANYE rotary airlock valves can be configured for different materials, capacities, pressure conditions, temperature requirements and industry standards.

A: A rotary airlock valve works by using a rotating rotor with multiple pockets inside a precision-machined housing. When material enters the valve inlet, it fills the rotor pockets. As the rotor turns, the material is carried to the outlet and discharged into the next process stage or conveying line.

At the same time, the close clearance between the rotor and the valve body helps reduce air leakage between the inlet and outlet. This allows the rotary valve to provide both material feeding and airlock functions in pneumatic conveying and dust collection systems.

The performance of a rotary airlock valve depends on several factors, including rotor design, machining precision, material characteristics, pressure difference, operating temperature, sealing structure and rotational speed.
