The Woodward SPC (Servo Position Controller) is a field-programmable servo-valve driver that accepts DeviceNet or 4–20 mA position demand signals and accurately positions proportional or integrating servo-valves. Designed for steam and gas turbine fuel valve control, the SPC provides the accuracy, responsiveness, and redundancy required for critical turbomachinery applications.
