Function of electric actuators
Signal response: Receive PLC, DCS or manual control signals and convert them into mechanical motion.
Torque output: Provide sufficient torque to overcome medium pressure and friction resistance.
Position feedback: Most are equipped with position sensors (such as potentiometers or encoders) to feed back valve position signals to the control system.
Protection function: Overload protection, limit switches, etc. to prevent motor damage.
