● Overview
DKZ type straight stroke electric actuator with DDZ-Ⅲ type instrument supporting the use and assembly can also be equipped with instrumentation and TA instrument . It is powered with 220V power supply , to accept a unified standard signal 4-20mA.DC, this input signal into a corresponding linear displacement axis , automatically operated valve or other agencies , such as the completion of the terminal automatically adjust task, or with now with electric operation manual remote . Widely used in power plants, steel mills, chemical industry , light industry and other industrial sectors conditioning system .
The instrument has a continuously adjustable , manual remote control , local hand- operated three control methods .
Use straight trip DKZ type electric actuator automatically adjusts the system to be equipped with ZPE-3101 servo amplifier , in order to achieve automatic control system manual ← → automatic bumpless the DFD-1000 electric actuator .
