‌Electromagnetic butterfly valves are designed for use with electric actuators, featuring low closing torque, sensitive operation, reliable performance, large diameter, and light weight. They are extensively applied in industrial sectors such as metallurgy, building materials, power, petrochemicals, and light industry, in fans, air conditioners, electrostatic precipitators, and various large pipelines. Primarily used for electric or manual adjustment and cutoff of dust and gases.

Structural characteristics

The electric butterfly valve is composed of main components such as the valve body, butterfly blades, valve shaft, linkage mechanism, and drive unit. Its operating principle involves the drive unit outputting torque, which is then transmitted to each valve shaft through the linkage mechanism. The rotation of the valve shafts drives the butterfly 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 butterfly blades consist of several blades that move around their respective rotating axes. The shaft ends are sealed with flexible graphite woven filler, which features high-temperature resistance and self-lubrication properties.

Application Scenario

Electromagnetic butterfly valves are widely used in ventilation and environmental protection projects in industries such as metallurgy, building materials, chemicals, power stations, and glass, in dust-laden cold or hot air gas pipelines. They are particularly suitable for applications with large diameters, high flow rates, and low pressure differences, and can be used as flow control or cutoff devices for gas mediums. Additionally, electromagnetic butterfly valves can be paired with various actuators to form equipment with different performance, meeting various industrial requirements.
