Manual ventilation butterfly valve
Manual ventilation butterfly valve is welded with carbon steel. It has the advantages of reasonable structure, wear resistance, small flow resistance loss, flexible operation, clear indication direction, convenient maintenance and long service life. It can be installed horizontally or vertically. Equipped with a worm gear transmission device, the switch is easy to open and close and the valve opening can be adjusted arbitrarily, making it ideal equipment for regulating flow rate.
