Pneumatic ventilation butterfly valve is a device used as a gas medium to adjust the flow or shut off. It is generally suitable for ventilation and dusty cold air or hot air gas pipelines in industry, metallurgy, environmental protection and other industries.
The pneumatic actuator of the pneumatic ventilation butterfly valve has double-acting and single-acting (spring return), gear transmission, safe and reliable; with rapid opening and closing, and small operating torque.
1. Reasonable design, unique structure, light weight, rapid opening and closing.
2. The operating torque is small, and the use is simple and convenient.
3. Geared double pistons, large output torque and small volume. The rack-type connection can adjust the opening angle and rated flow.
Pneumatic ventilation butterfly valve, also called pneumatic damper, is widely used in many fields such as petroleum, chemical industry, metallurgy, water and electricity.When installing the pneumatic damper, it can be installed horizontally or vertically, and the flange of the air flow direction marked by the damper and the flange of the pipeline should be bolted together.Washer of the same specification is required.
