. Motor position control without slidewire Feedback.
MOTOR VALVE
Motor position is achieved by using time proportional control
without the need for slidewire feedback from the motor shaft.
Slidewires wear over a period of time, which can result in
poor or intermittent control. This type of control reduces
maintenance requirements and removes the need for the
controller to be calibrated to the motor feed back
potentiometer.
