ZKJ type angular travel electric actuator (actuator)

ZKJ and DKJ type angular stroke electric actuators can be used with 90-degree motion valves such as dampers, ball valves and butterfly valves. They can also be used with assembly instruments and display adjustment instruments. It is powered by 220V power and accepts unified standard signals. 0mA, 4~20mA DC, which becomes the angular displacement corresponding to the input signal, can be used in the regulation system of the automation industry departments such as power plants, steel plants, chemical industry and light industry. The instrument has three control modes: continuous adjustment, manual remote control and local hand operation. The automatic adjustment system of the ZKJ-type quarter-turn electric actuator is equipped with the DFD-1000 electric operator, which can realize the manual adjustment of the adjustment system: automatic bumpless switching. Its characteristics: the position transmitter has constant current output characteristics, the output current is 0 ~ 10mA \ 4-20mA DC can withstand the frequent start and stop of the servo motor brake part of the missile is supported by the vacuum aging treatment, the average service life can reach six years

I. Overview
DKJ type angular stroke electric actuator is the execution unit in DDZ-II and III series instruments. It is used with DDZ-II and III type control unit instruments. It is powered by AC power and accepts a unified standard signal of 4~20mA. Dc (or 0 ~ 10mA, dc), the input signal and the feedback signal of the position transmitter, after the comparison of the servo amplifier, the output switch signal, drive the motor, after mechanical deceleration, convert the input signal into the corresponding output shaft angular displacement : Automatically operate the damper flapper, butterfly valve, ball valve and other devices to complete the automatic adjustment task of the system: it is widely used in the regulation system of industrial sectors such as power station, metallurgy, petroleum, chemical, machinery, light industry, textile, food and medicine. .
