Dust butterfly valve

One Product Introduction:
Dust butterfly valveComposed of two semi valve bodies cast by gravity, the semi valve bodies are made of aluminum alloy material, and the rotary valve plate is made of polymer material with good sealing performance. A circular flange with the same top and bottom, featuring a top flange and a folded component, suitable for a flexible sleeve.Dust butterfly valveMainly used for opening and closing material boxes, hoppers, and silos containing powdered or granular materials. It can be applied to the processing of all powdered and granular materials. The valve uses the material's own gravity to intercept and pneumatically transport dry materials. It can be installed under hoppers, bins, silos, spirals, or other types of conveyors, as well as connected to pneumatic conveying pipelines. Due to its unique structure and the use of engineering materials, this valve has always been a very economical and efficient choice.

2、 Product features:
1. Easy and quick opening and closing, labor-saving, low fluid resistance, and can be operated frequently.
2. Simple structure, small external dimensions, short structural length, small volume, light weight, suitable for large-diameter valves.
3. It can transport mud and accumulate less liquid at the pipeline mouth.
4. Under low pressure, good sealing can be achieved.
5. Good regulation performance.
6. When fully open, the effective flow area of the valve seat channel is larger and the fluid resistance is smaller.
7. The opening and closing torque is relatively small, and due to the fact that the butterfly plates on both sides of the shaft are subjected to the same medium effect, the direction of torque generated is opposite, making opening and closing more effortless.
8. The sealing surface material is generally made of rubber or plastic, so it has good low-pressure sealing performance.
9. Easy to install.
10. Flexible and labor-saving operation, available in manual, electric, pneumatic, and hydraulic modes.
