● Overview
Electric actuator in automatic control system , according to the change control instrument signal to adjust an instrument to manipulate change mechanism ( valve ) of displacement .
DKJ type rotary electric actuator can be used with transmitters, regulators and other instruments supporting the use of its power as the power to accept 4 ~ 20mADC or 0 ~ 10mADC signal , this input signal is converted into the corresponding corner displacement ,
Automatically operated dampers , butterfly valves, ball valves and other regulatory agencies to complete the task of automatic adjustment , or equipped with electric operation to achieve remote manual control , the instrument
Table can be widely used in power plants , steel mills , chemical industry, light industry and other industrial sectors conditioning system .
The instrument has a continuously adjustable , remote manual control and local hand operation three control methods .
The instrument for non-corrosive gases , the ambient temperature is -25 ℃ ~ +70 ℃, relative humidity ≤ 95% of the sites.
