DKJ series electric actuators are DDZ type electric element combined type actuator for checking and modulating instrument. The actuator receive signal from modulating or transducing unit, carry out modulating task automatically. The products are widely used in fields of oil, metallurgy, chemical industry, power plant, light industry, water treatment, building materials, urban construction, etc.
Automatic regulating system of DKJ series electric actuators matched DFD-05, DFD-07 or DFD-09Ⅱ（DFD-0500，DFD-0700，DFD-0900Ⅲ type）electric operating station can non-interference switch between regulating system manual operation and automatic operation. 
Position transmitter adopt new-style sensing element with novel structure design. Constant-current characteristic, output current precision and reliability are all much better than differential transformer. For the past few years, along with components and parts technology speed development, actuator adopt modularization to instead of separate element structure. Reliability and stability are better. The advantage are anti-knock, anti-corrosion, anti-oxidation, etc. Except explosion proof type, collocate terminal electric limit switch. Satisfied customer’s modulating requirement.
