‌Electric Louver Valve is a valve designed for use with electric actuators, featuring low opening/closing torque, sensitive operation, reliable performance, large bore, and light weight. It is widely used in industrial departments such as metallurgy, building materials, electricity, petrochemicals, and light industry, in fans, air conditioners, electrostatic precipitators, and various large pipelines. It is primarily used for electric or manual adjustment and cutting of dust and gases.‌

Structural Features

The electric louver valve is composed of main components such as the valve body, louver blades, valve shaft, linkage mechanism, and driving unit. Its working principle involves the driving unit outputting torque, which is then transmitted to each valve shaft through the linkage mechanism. The rotation of the valve shafts drives the louver blades to rotate, thereby altering the cross-sectional area of the pipeline to regulate the flow rate of the medium or to cut off the medium. The louver blades consist of several blades that rotate around their respective axes. The shaft ends are sealed with flexible graphite woven packing, featuring high-temperature resistance and self-lubrication properties.

Application Scenarios

Electric butterfly valves are widely used in the ventilation and environmental protection projects of industries such as metallurgy, building materials, chemicals, power plants, and glass, in dust-containing cold air or hot air gas pipelines. They are particularly suitable for large-diameter, high-flow, and low-pressure differential applications, and can be used as gas medium flow regulation or cutting-off devices. Additionally, electric butterfly valves can be paired with various actuators to form equipment with different performance, meeting various industrial needs.
