Product Overview
The pneumatic dust butterfly valve consists of a special side-push cylinder designed by our company and an aluminum alloy butterfly valve. Its body is composed of a high-pressure aluminum alloy body, a deformable wear-resistant rubber ring, and a polymer wear-resistant composite disc. It is an ideal product for opening and closing material boxes, hoppers, and silos containing powdered or granular materials. Widely used in cement powder transmission in concrete mixing plants, gravity dust removal in steel plants, and other fields. Due to its special structure and the application of engineering materials, it is always a highly economical and efficient choice. The overall design of the pneumatic dust butterfly valve is compact, with over 80% of the components made of aluminum alloy, making it lightweight. It adopts a special side-push cylinder designed by our company, which can rapidly cut off or open materials in the silo or hopper. The cylinder uses a Y-ring + O-ring combined sealing structure, greatly increasing its service life. The valve body consists of two high-pressure die-cast half-bodies made of aluminum alloy. The valve ring is designed in a U-shape, enhancing its deformable sealing ability, featuring automatic wear compensation. It is wear-resistant, highly efficient, and achieves zero leakage. The aluminum alloy rotating disc and valve shaft are integrated by die-casting, making installation more convenient. It features a top flange and a detachable pipe connector, suitable for connecting a flexible sleeve for easy discharge connection. This product is usually installed below hoppers, material boxes, silos, screw pumps, or other types of conveyors, as well as connecting pneumatic conveying pipelines.

Product Features

1. Single-flange valve, with a top flange and a beaded component, suitable for connecting flexible sleeves.

2. Double-flange valve, with identical flanges at the top and bottom.

3. The valve body is made by gravity casting, which has higher strength than die-cast bodies.

4. The rotating disc uses polymer material, which is wear-resistant.

5. Few components, lightweight, and easy to handle.
