The Sanitary Ball Valve device is a combination of an electric actuator and a ball valve. The electric actuator receives an external control signal, driving the ball valve core to rotate, achieving the functions of opening and closing the pipeline medium and regulating the flow rate. It has the advantages of simple operation, rapid response, high control accuracy, and a high degree of automation. It is widely used in pipeline systems in various fields such as petroleum, chemical industry, electric power, metallurgy, water supply and drainage.
