ITT Controls - Valves and Actuators

Electric actuator consists of electric motor, speed reducer, position limit mechanism and over torque protection mechanism and position feedback device.

Electric actuator is actuated by motor, as DC current for control and feedback signal.

When the upper instrument or the computer send out the control signal, the electric actuator will act in proportion according to the value of signal, and open valve or damper to the corresponding opening through the output shaft, then feedback the opening signal to the control room, accordingly the system accomplishes regulating function.

Electric actuator can also be used by equipping with operator, servo amplifier and other instruments.

Function of Operator:
1. Transmitting the signal, providing the visual input and output signal value for the user in the control room, making watching the valve position convenient.
2. Used for operating the electric actuator directly to instead of manual operation in case of control signal failure or system maintenance.

Function of Servo Amplifier ( Positioner )
Amplifying Signal. It accepts the 4-20mA control signal, and amplify the signal to the high voltage signal to control the forward-reverse transfer of motor of the actuator.


When electric actuator connected with various valve bodies, they form as various kinds of valves. You can buy electric actuators at ITT Controls. Please inform at our sales department via info@ittcontrols.com
