Pneumatic Cast Steel Stainless Steel Ventilation Flange Butterfly Valve

Product Overview

Pneumatic ventilated butterfly valve is used in the ventilation pipe is a kind of non-closed rotary butterfly valve, using the center line type disc plate and short structure steel plate welding structure form design and manufacture, as a gas medium flow regulation or switch control. Pneumatic adjustable ventilation butterfly valve flow resistance is small, flow coefficient is large, light weight, fast opening and closing, and valve positioner supporting the use of proportional adjustment can be realized, especially for large diameter, large flow boiler kiln flue gas control.

Advantages of Pneumatic Adjustable Ventilation Butterfly Valve

1. It can control the valve switch and adjustment from a distance, which can save time and labor cost.

2. There is no connecting rod, bolt, etc. inside, reliable work, long service life. Can be installed in multiple positions, not affected by the media flow direction.

3. It is designed and manufactured by adopting the new structural form of welded centerline disc plate and short structural steel plate, with compact structure, light weight, easy installation, small flow resistance, large flow capacity, avoiding the influence of high temperature expansion, and light operation.
