The name of the butterfly valve comes from the butterfly plate of the wing-like structure, and the butterfly plate is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate can be opened and closed only by rotating 90° around the axis.

Butterfly valve has simple structure, small size and light weight. It consists of only a few parts. And it only needs to be rotated 90° to open and close quickly, and the operation is simple. The valve has good fluid control characteristics.

When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance for the medium to flow through the valve body. The pressure drop across the valve is therefore very small. During the closing movement of the valve, the disc rotates toward the closed position, and the flow velocity of the medium gradually decreases. The valve has good flow control characteristics.
