GT series angular stroke electric actuator
OverviewGT series electric actuators are rotary electronic valve drive devices that control valves through external power switching or input DC current signals.
This series of electric actuators is powered by a low-speed synchronous motor and outputs torque through a gear reduction mechanism. We use high-precision and reliable potentiometers for position feedback output, and set upper and lower limit limits. We can also provide intermediate position contact output through protocol.
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.
