DKJ-B series flameproof rotary electric actuator for industrial process measurement and control system of the terminal control device, he can control the system output signals into components of the angular displacement to control the position of the valve closure or other adjustment software agency is charged with the media in accordance with the provisions of the state system work. 

 DKJ-B series flameproof rotary electric actuator according to national standards GB3836.1-2000 and GB3836.2-2000 "Electrical apparatus for explosive gas atmospheres" explosion-proof design and manufacture and identified by the national authorities the qualified. The explosion-proof products for the explosion-proof, explosion-proof grade dIIBT3, burst transmission can contain no more than the ability of gas Class B Class II T3 group workplace. 

 DKJ-B series of flameproof electric actuator control mode in accordance with proportional and integral divided. Proportional electric actuator control signal and the system output of pieces of position on the feedback signal to change the output file to compare the trip to make it proportional to the input signal. Common form of proportional type actuator position by the GAMX locator and integral component of electric actuators, electronic electric actuator for the whole structure of proportion, integral electric actuator by the servo motor, reducer and position transmitter composition, it is both the location and type of locator GAMX composition of electric actuator, electric operator can meet with the valve or other regulating agencies to achieve remote operation. 

 DKJ-B series flameproof rotary electric actuator installation form is divided into common type (base installation, by the output arm through the connecting rod and valve connections and other regulatory agencies) and the direct type (flange mounting, and adjust the output shaft institutions shaft direct docking) 

 DKJ-B Series Proportional flameproof rotary electric actuator connected with DFD-1300 electric operation can be achieved: manual "automatic disturbance switch, automatic operation and manual" remote "operation. 

 DKJ-B series flameproof rotary electric actuator safety and reliability, installation, commissioning and operation, easy maintenance, widely used in energy, metallurgy, chemicals, building materials industry, in industrial measurement and control systems engineering play an important role.
