Pneumatic cement butterfly valve structure characteristics and manufacturing standards

pneumatic cement butterfly valve DX is specially used for powder, granular material of industrial products. Pneumatic cement butterfly valve pneumatic valve rubber seal form a soft seal to make it very suitable for the powder, granular materials applications, especially for wear resistant materials. In need of gravity blanking or pneumatic conveying powder, granular materials handling system, pneumatic butterfly valve is often installed in the hopper, silos, screw conveyor export and gas pipe. According to the application requirements, can separate optional drive handles or cylinder drive suite. Easy installation and maintenance etc. , is a kind of cost - High efficiency of powder plate, nitrile butadiene sealing ring, covered with wear-resisting polymer materials. Manual, electric, pneumatic, gear motor drive device such as a driver and mutual exchange. The weight of the compact structure, lightweight, make you install and use more convenient; Industrial design, combined with the use of composite pneumatic valve plate provides the best sealing effect and the longest service life.
