9907-1200 WOODWARD CPC-II 10 bar, Zone 2, simplex, Enhanced Dynamic version (current-Pressure Converter, second generation) is an electro-hydraulic pressure regulating valve controller designed to position single-acting steam turbine valve servos. With excellent accuracy and resolution, this CPC is ideal for steam turbine valve control and associated turbine speed and load control.

Features

Pressure Control: Accepts a 4–20 mA pressure demand signal to accurately control oil pressure and position single-acting steam turbine governor valves.
Redundancy: Configurable to accept redundant pressure demand inputs from one or two controllers.
Failsafe Mechanism: Internal valve-return-spring forces the CPC to a failsafe position, ensuring safe closure of turbine control valves in the event of an internal unit failure.
Robust Design: Features a strong actuator, corrosion-resistant materials, a single moving rotary valve, and a self-cleaning port design.
