COVNA Powder/Cement Flange Electric Butterfly Valve
COVNA Electric butterfly valve is mainly used for powder material hopper and a switch box, powdery or granular materials is the silo. Can be applied to all powdery and granular materials, using gravity closure material valve and pneumatic transmission. Dry materials can be installed in the hopper bins, silos, below or other types of spiral conveyor, and connected with the pneumatic conveying pipeline. Because of the special structure of the valve and the use of engineering materials, it is always a very economical and efficient choice.
