The pneumatic powder butterfly valve is composed of two half-valve bodies made by gravity casting. The half-valve body is made of aluminum alloy material, and the rotary valve plate is made of polymer material, which has good sealing performance. The top and bottom round flanges are the same, with a top flange and a flanged part, suitable for a flexible casing.
Pneumatic butterfly valves are mainly used to switch bins, hoppers and silos containing powder or granular materials. It can be applied to the treatment of all powdery and granular materials. The valve uses the gravity of the material to intercept the flow and pneumatically convey dry materials. It can be installed under hoppers, bins, silos, spirals or other types of conveyors, and connected to pneumatic conveying pipes. Due to the special structure of this valve and the use of engineering materials, it is always a very economical and highly efficient choice.
Features:
BL1F single flange valve, with top flange and flange parts, suitable for connecting flexible casing
BL2F double flange valve, the top and bottom are the same flange
The valve body made by gravity casting is stronger than the die-cast valve body
The rotary valve plate is made of polymer material, which is wear-resistant
Few components, light weight, easy to handle
