The BY42 electric louver butterfly valve is an industrial automation control device widely used in metallurgy, chemicals, building materials, power plants, and environmental protection industries. The valve mainly consists of a body, louver blades, shafts, and an electric actuator. Driven by the electric actuator, multiple groups of louver blades rotate synchronously within a 90° range to precisely regulate or shut off the flow of air, flue gas, or dust-laden gas in the pipeline. Due to its multi-axis louver structure, the valve features low flow resistance, rapid opening and closing, short structural dimensions, and light weight, making it especially suitable for large-diameter, high-flow, and low-pressure-differential systems.

1.Compact and lightweight design:The ultra-short face-to-face length significantly reduces the mechanical load on the pipeline compared to traditional control valves.
2.Low flow resistance and high efficiency:The streamlined blade design ensures a near-straight flow path when fully open, resulting in minimal pressure drop.
3.Low operating torque and smooth motion:The multi-axis linkage balanced structure offsets most of the fluid impact force.
4.Temperature and corrosion resistance:Available in carbon steel, stainless steel, or wear-resistant steel to adapt to high-temperature flue gas or corrosive conditions.
5.Intelligent actuation:Equipped with an intelligent actuator that supports 4-20mA signal regulation and real-time position feedback.
6.Reliable sealing performance:Optional sealing strips provide effective shut-off in both ambient and high-temperature environments.
7.Long service life:Core rotating parts utilize self-lubricating bearings to reduce mechanical wear, ensuring long maintenance cycles.
8.High degree of customization:Available in rectangular or circular structures to meet diverse installation requirements of process piping.
