DKZ series electric actuators are terminal control devices for industrial process measurement and control systems. They can convert the control signal of the system into the angular displacement and linear displacement of the output shaft, control the position of valves and other shut-off parts or other regulating mechanisms, and make the controlled medium work according to the specified state of the system.
Electric actuators are divided into proportional and integral types according to the control method. The proportional actuator consists of an electric servo amplifier and an integral actuator. It can compare the control signal of the system with the feedback signal about the position of the output shaft (closed-loop control) to change the stroke of the output shaft so that it is proportional to the output signal. The integral actuator consists of a servo motor, a reducer and a position transmitter. It can cooperate with the electric operator to realize remote operation of valves or other regulating mechanisms.
