YT1000 series of electrical and pneumatic control valve positioner supporting Use, constitute a closed-loop control loop. The control system to the DC current signal is converted to drive the valve control valve signal to control the action of the control valve. At the same time according to the opening of the control valve feedback, so that the valve position can be controlled by the system output signal for the correct positioning. The electrical positioner can be used for single acting (spring return type) and double acting pneumatic actuators.
