First, the use of 
 DKJ-D Series electric actuator is a common type in the original factory DKJ electric actuator on the basis of absorbing foreign advanced technology, the application of new techniques from abroad, a new device developed with intelligent features full electronic control circuit and institutional integration get new products. DKJ-D electric actuator can be directly adjusted to accept various types of DCS or computer unit 4 ~ 20mA or 1 ~ 5V, automatic control of dampers, valves, baffles and other regulatory agencies, the servo amplifier without additional configuration, can be widely applied in electronics, metallurgy, petroleum, chemical and other industries.
