First, manual flange ventilation butterfly valve overview:
The manual flanged butterfly valve is a non-closed butterfly valve. The ventilation 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 large in circulation. Avoid the effects of high temperature expansion and operate lightly. 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. Ventilation butterfly valve is a non-closed butterfly valve. 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.
