Design Features:
The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline.
The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics.
