Electric actuator

Industries such as electricity, metallurgy, petroleum, chemical, food, textile, papermaking, pharmaceuticals, water plants, and sewage treatment
The DKJ series actuator is a driving device for valve opening, closing, or regulating control, suitable for valves such as butterfly valves, ball valves, plug valves, and dampers that rotate 90 degrees. This series of electric actuators can be remotely controlled or operated on-site. Widely used in industries such as power, metallurgy, petroleum, chemical, food, textile, papermaking, pharmaceuticals, water plants, and sewage treatment.

The DKJ series electric actuator is a terminal control device for industrial process measurement and control systems. It can convert the system's control signals into angular displacement and linear displacement of the output shaft, control the position of flow blocking components such as valves or other regulating mechanisms, and make the controlled medium work according to the system's specified state. Electric actuators are divided into feedback and regulation types according to their control methods. The regulating actuator consists of an electric servo amplifier and an integral actuator, which can compare the control signal of the system with the feedback signal about the output shaft position (closed-loop control) to change the stroke of the output shaft in proportion to the output signal. Feedback type actuators consist of servo motors, reducers, and position transmitters, which can be used in conjunction with electric operators to remotely operate valves or other regulating mechanisms
The DKJ series is manufactured in accordance with the national standard GB11922-89 "For Industrial Process Measurement and Control Systems" of the People's Republic of China.
