Hydraulic Wafer Flange Butterfly Valve

The hydraulic wafer flange butterfly valve is a kind of valve hydraulic device. It is made up of a hydraulic actuator and a butterfly valve. Therefore, it has the advantages of simple operation and simple structure, small size and weight. Light, consisting of only a few parts. It was subsequently widely used in chemical, pharmaceutical and other industries. The working principle of the hydraulic butterfly valve is to drive the valve stem through the hydraulic device, so that the butterfly plate produces a 90° rotary motion to achieve the valve switch.
