Beschreibung
Doebritz conventional blow-through rotary valve is specifically developed for pressure conveying applications where powders must be safely introduced into conveying pipelines under potentially explosive conditions. Its blow-through design allows conveying air to pass through the rotor, improving material dispersion while minimizing buildup and ensuring continuous flow.
Built with explosion-proof materials and a robust sealing system, the valve effectively prevents gas leakage and dust ingress, significantly reducing the risk of ignition. The integrated grounding structure eliminates static electricity accumulation, while optional temperature monitoring devices provide real-time protection against overheating, ensuring compliance with strict industrial safety requirements.
Designed for durability and long-term operation, the valve features corrosion-resistant, high-temperature sealing components and precision-machined internals to maintain consistent performance under high-pressure and harsh working conditions. It is widely used in industries such as chemical processing, pharmaceuticals, food production, and environmental systems where safety and reliability are critical.
As an experienced rotary valve manufacturer, Doebritz offers full customization to meet specific project requirements, including valve size, material selection (carbon steel, stainless steel, special alloys), sealing configurations, and explosion-proof certifications tailored to different applications and regional standards.

Q: What is a blow-through rotary valve used for?
A: A blow-through rotary valve is used in pneumatic conveying systems to introduce powder or bulk materials directly into a pressurized conveying line. It ensures continuous feeding while maintaining an effective airlock, preventing pressure loss and material leakage.Q: Is this rotary valve suitable for explosive environments?
A: Yes. This valve is designed with an explosion-proof structure and complies with international standards such as ATEX and IECEx. It features anti-static grounding, high-integrity sealing, and temperature control options to ensure safe operation in hazardous environments.Q: What is the difference between blow-through and drop-through rotary valves?
A: Blow-through rotary valves inject material directly into a pressurized conveying pipeline, making them ideal for dense or dilute phase conveying. In contrast, drop-through valves rely on gravity feeding and are typically used in low-pressure or non-pressurized systems.Q: How does the valve prevent dust leakage and contamination?
A: The valve uses advanced sealing technology with high-temperature and corrosion-resistant materials to ensure tight airlock performance. This minimizes internal gas leakage and prevents dust escape, ensuring a clean and safe working environment.Q: Can the rotary valve be customized for specific applications?
A: Yes. As a professional manufacturer, Doebritz offers full customization options, including valve size, rotor design, material (carbon steel, stainless steel, special alloys), sealing configuration, and explosion-proof certifications tailored to your process requirements.Q: What industries is this explosion-proof rotary valve suitable for?
A: This valve is widely used in industries requiring safe powder handling, such as chemical processing, pharmaceuticals, food production, and environmental engineering, especially where combustible dust or explosive gases are present.Q: How is maintenance performed on this rotary valve?
A: The valve is designed for easy inspection and maintenance, with durable components and accessible structure. Regular checks of sealing parts, grounding systems, and temperature monitoring devices ensure long-term safe operation.
