Full Lined Manual Operated Wafer Butterfly Valve
The full lined manual operated wafer buttergly valve is a simple structure of the regulating valve. This wafer butterfly valve can be used for low pressure pipeline medium switching means that the closing element (valve or butterfly plate) is a disk, and rotates around the butterfly valve shaft to open and close. This manual wafer butterfly valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals. In the pipeline mainly cut off and throttling effect. Butterfly valve opening and closing device is a disc-shaped butterfly plate, rotating around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.
