Electric ball valve actuator is an indispensable driving control device for realizing program control, automatic control and remote control of electric ball valve, and its movement process is controlled by stroke, torque, etc. Since the working characteristics and utilization of electric ball valve actuators depend on the type and characteristics of the ball valve, the correct selection of the ball valve actuator is essential to prevent overloading. The output torque of the actuator is the most important parameter for selecting an electric actuator, and the output torque of the actuator should be 1.2~1.5 times the maximum operating torque of the selected ball valve. Secondly, according to the different conditions of use of the ball valve, select the appropriate opening and closing speed, which can prevent the ball valve actuator from opening and closing too fast and causing water hammer.
