Woodward Steam Turbine Actuation
Steam Turbine Servo-Valve Driver
SPC (Servo Position Controller)
Woodward’s SPC (Servo Position Controller) is a servovalve driver that accepts a 4–20mA position signal and accurately positions proportional or integrating servovalves.
The SPC is a field programmable servo driver that controls one integrating or proportional servovalve, and accepts single- or dual-feedback signals for valve position sensing. The SPC has the required accuracy, responsiveness, and redundancy required for steam or gas turbine fuel valve control.
