Pneumatic ventilation butterfly valve Overview:

Pneumatic ventilation butterfly valve is a kind of non-closed rotary butterfly valve used in ventilation pipe. It is designed and manufactured by welding the medium plate with the short structure plate. It is used as the flow regulation or switch control of the gas medium. Pneumatic ventilation butterfly valve flow path resistance is small, large flow coefficient, light weight, fast opening and closing, with the valve positioner used together, can achieve proportional adjustment, especially suitable for large diameter, large flow boiler flue gas control.

Pneumatic ventilation butterfly valve advantages:

1. Can remotely control the valve switch, adjust, to save time and labor, save labor cost.

2. No connecting rod, bolts, etc., reliable work, long service life. Can be installed in multiple stations, not affected by the flow of media.

3. It is designed and manufactured by using the new structure form of medium line plate and short structure steel plate welding. It has compact structure, light weight, easy installation, small flow resistance, large circulation, avoiding the influence of high temperature expansion and light operation.
