Pneumatic powder butterfly valve is mainly used for opening and closing hoppers, hoppers and silos containing powder or granular materials. It can be applied to the processing of all powder and granular materials, and can be installed in hoppers, hoppers, silos, Below a screw or other type of conveyor. Single flanged valve with top flange and hem fittings, suitable for connecting flexible casing, double flanged valve, same flange top and bottom, gravity cast The formed valve body has higher strength than the die-cast valve body. The rotary valve plate is made of polymer material, which is wear-resistant, has few components, and is lightweight and easy to handle.
