Pneumatic valve powder silo mixing station Features: single flange valve with top flange and folding parts, suitable for connecting a flexible sleeve double flanged valves, top and bottom flanges of the same cast from gravity The body, higher than the die-cast body strength rotary valve plate using polymer materials, wear-resistant and less components, lightweight, easy to handle powder mixing plant silos pneumatic valve is mainly used for switching bins, hoppers and equipped Silos powdery or granular materials. Can be applied to deal with all powdery and granular materials, the use of the material itself gravity valve closure and pneumatic transport of dry materials. Can be installed below the hopper, bin, silo, spiral or other type of conveyor, and connecting the pneumatic conveying line. Because of the special structure and the use of this valve engineering materials, it is always a very economical and very efficient choice. Pneumatic valve powder mixing plant silos by gravity casting made of two half body composition, half body aluminum alloy material, the rotary valve plate using polymer materials, has a good seal. Top and bottom of the same circular flange, having a top flange and a hemming member for a flexible sleeve.
