Cheap butterfly valve quality

High quality butterfly valve has a unique shape when compared with other valve-valve.
Butterfly uses a round plate or ankle-operated disc for opening positions
full or completely closed with an angle of 90 °. This disk stays in the middle of the stream, and
connected to the ankle through the shaft. When the valve is closed, the Disk is perpendicular
with flow direction, so that the flow is blocked, and when the valve is opened the wafer is parallel to the flow, so that the material can flow through the valve.
