EA series angular stroke electric actuator
overviewThe EA series electric actuator is a rotary electronic valve drive device that controls the valve through external power switching or input of DC current signals.
This series of electric actuators is powered by an internal motor and equipped with wear-resistant worm gears and worm gears for final reduction. High precision and reliable potentiometers are used for position feedback output, and upper and lower limit limits are set.
This series of electric actuators adopts a patch mounted large-scale integrated circuit to make servo amplifiers, forming proportional varieties (i.e. with E), and controls the valve through 4-20mA or 1-5V signals.
