The wafer-type butterfly valve has a simple structure, small volume and light weight, and is composed of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, with simple operation. At the same time, this valve has excellent fluid control characteristics.
The disc of the turbine butterfly valve is installed in the diameter direction of the pipeline. Inside the cylindrical channel of the butterfly valve body, the disc-shaped plate rotates around the axis at an Angle ranging from 0° to 90°. When it rotates to 90°, the valve is fully open.
