DKJ-D (DY-J) series electric actuator is a new product of our factory. On the basis of the ordinary DKJ electric actuator, it incepts advanced foreign technology, and adopts new foreign technology, new devices to form this fully electronic product with intelligent functions which is the combination of control circuit and actuator.

DKJ-D (DY-J) electric actuator can receive directly computer DCS or all kinds of regulating units 4~20mA or 1~5V , and control various regulating mechanisms such as damper, valve, baffle, etc. There is no need to install servo amplifier additionally. It can be widely used in electron, metallurgy, oil, chemistry.

DKJ-D (DY-J) series electric actuator has the function of operating manually. It can adjust the actuator on the spot. If plus the DFD type electric actuator, it can realize the " manual-automatic" switchover of        system without disturbance, and remote manual control to the controlled plant.
