Electric actuator DKJ-310 DKZ-3100 DKJ-410 Intelligent angular stroke electric actuator Item NO.: 1941932

1、 Overview

DKJ angular stroke electric actuator is the executive unit of DDZ - Ⅱ and Ⅲ series instruments, which is used together with DDZ - Ⅱ and Ⅲ control unit instruments. It takes AC power supply as power, receives unified standard signals 4 ~ 20mA, DC (or 0 ~ 10mA, DC), input signals and feedback signals from position transmitter, outputs switch signals after comparison with servo amplifier to drive motor, After mechanical deceleration, the input signal is converted into the corresponding angular displacement of the output shaft: automatically operate the damper, butterfly valve, ball valve and other devices to complete the automatic adjustment task of the system: it is widely used in the adjustment system of industrial departments such as power station, metallurgy, petroleum, chemical industry, machinery, light industry, textile, food and medicine
