Ventilation butterfly valve
The Ventilation Butterfly Valve is a specially designed flow control valve widely used in ventilation, air duct, and industrial gas systems. It is engineered for efficient air flow regulation, reliable shut-off, and smooth operation under low-pressure and large-volume airflow conditions.
Featuring a lightweight structure, low operating torque, and excellent corrosion resistance, the ventilation butterfly valve is suitable for controlling air, exhaust gas, flue gas, and non-corrosive industrial gases. The valve can be equipped with manual, pneumatic, electric, or intelligent actuators to meet different automation requirements.
Compared with traditional air control valves, the ventilation butterfly valve offers advantages including compact design, easy installation, fast response, low maintenance cost, and long service life.
