First, the ventilation flange pneumatic butterfly valve overview:
Ventilation flange pneumatic butterfly valve is a non-closed pneumatic butterfly valve. The ventilation pneumatic butterfly valve is designed and manufactured by a new structure of medium-line disc and short-structure steel plate. It is compact in structure, light in weight, easy to install, small in flow resistance and flux. Large, avoiding the effects of high temperature expansion, and easy to operate. Pneumatic ventilation butterfly valve has no connecting rods, bolts, etc., reliable operation and long service life. Can be installed in multiple stations, independent of the flow of media. Pneumatic ventilation butterfly valve is a non-closed butterfly valve. Pneumatic ventilation butterfly valve is widely used in building materials, metallurgy, mining, electric power and other pipelines to connect, open and close or adjust the amount of media.
