DKJ-210 DKJ-310 DKJ-410 DKJ-510 Electric actuator

Overview

DKJ angle travel electric actuator is the actuating unit of DDZ - Ⅱ and Ⅲ series instruments, which is used together with DDZ - Ⅱ and Ⅲ control unit instruments It is powered by AC power supply and receives unified quasi 4~20mA, dc (or 0~10mA, dc), feedback of input and position transmitter. After comparison of servo amplifier, it outputs the switch and drives the motor. After mechanical deceleration, it converts the input into corresponding output shaft angular displacement: it automatically operates damper, butterfly valve, ball valve and other devices to complete the automatic adjustment task of the system: it is widely used in power plants, metallurgy, petroleum, engineering In the regulation system of machinery, light industry, textile, food, medical and other industrial sectors
