Mixing station with cement powder discharge butterfly valve is mainly used for powder silos switch bins, hoppers and equipped with powdery or granular materials. It 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. Double flange butterfly valve can be mounted below the powder hopper, bins, silos, screw or other type conveyors, and pneumatic conveying pipeline connection. Because of the special structure and the use of this valve engineering materials, it is always a very economical and very effective choice. Double Flange Butterfly Powder Features: single flange valves: with top flange and folding parts, suitable for connecting a flexible sleeve. Double flanged valves: the same top and bottom flanges. Body: made using gravity casting, die-cast body strength higher than the valve plate: Rotary, wear resistance, less restructuring items, lightweight, easy to handle powder discharge valve pneumatic Product Details Brand: Ouyang Model : DN150, DN200, DN250, DN300, DN350, DN400 Scope: concrete mixing stations and dry powder Synonyms: butterfly valve connection: flange material: cast aluminum Nominal diameter: 100-400 (mm) Medium : Air Pressure Range: 0.2Mpa Temperature: Maximum 80 ℃ Body Material: Semi-body aluminum alloy material, the use of polymer materials rotating body structure: vertical plate Transmission Type: Pneumatic Seal type: Soft sealing pneumatic actuator Configuration: CP101 Type
