Aluminum Alloy Pneumatic Dust Butterfly Valve

The Aluminum Alloy Pneumatic Dust Butterfly Valve is a specialized flow control device designed for powder and dust handling systems. It combines lightweight construction, quick response, and high sealing performance, making it ideal for applications in cement plants, silos, pneumatic conveying systems, and dust collection equipment. 

Key Advantages
Anti-Clogging and Dust-Resistant Design
The valve body features a streamlined internal structure to minimize dead zones where dust could accumulate. Some models are equipped with dust scraping mechanisms or air purge ports, allowing efficient cleaning of the disc and sealing surfaces.

Fast Opening and Closing for Efficient Control
The valve operates through a rotary disc motion (typically 0–90° rotation), which allows quick opening and closing within seconds. Its simple structure and short actuation stroke enable rapid response, reducing material retention and maintaining stable pressure in pneumatic conveying systems.

Compact Structure and Easy Maintenance
With a lightweight aluminum alloy body and compact size, the valve requires minimal installation space—ideal for confined dust conveying systems. The valve disc and sealing components are easy to disassemble and replace without special tools.

Reliable Sealing to Prevent Dust Leakage
Depending on the application, the valve uses resilient seals (rubber or PTFE) or metal sealing structures. Some models include dual-seal or dust-ring designs, effectively preventing fine particle leakage and maintaining system vacuum or pressure stability.

High Wear Resistance for Various Dust Types
Flow-contact parts such as the valve disc and body can be made of wear-resistant materials like cast steel, hard alloys, or ceramic-coated surfaces. This ensures durability when handling abrasive powders such as mineral dust, cement, or metallic particles.
