Handle butterfly valve has simple structure, small volume, light weight, only by a few parts.and only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the valve has good flow control characteristics.Butterfly valve in the fully open position, the butterfly plate thickness is medium flows through the body when the only resistance, thus produced by the valve pressure drop is small, it has good flow control characteristics.
