Cast Iron Line Fluorine Wafer Butterfly Valve
Butterfly valve, is a simple structure of the control valve, can be used for the low pressure pipeline medium switch control of butterfly valve is to close the disc, rotating around the valve shaft to achieve the opening and closing of a valve.
Valves can be used to control the flow of air, water, steam, corrosive media, mud, oil, and other types of fluid. It is mainly used for cutting and throttling in pipelines. Butterfly valve opening and closing parts is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulation.
