What is the electric actuator
The Electric actuator is a kind of driving device which can provide linear or rotational motion. It uses power supply and works under the control of ON/OFF or analog control signal (4-20mA). Its types include Quarter-Turn, Multi-Turn and Linear.
The electric actuator is used to drive the valve to any position of full opening or full closing.
It can be divided into two categories:
1) ON/OFF type, without stopping in the middle position.
2) Modulating type, can stop at any position in the middle, high precision, suitable for temperature, pressure, flow control system.
They include position induction device, moment induction device, electrode protection device, logic control device, digital communication module and PID control module, all of which are installed in a compact shell.
