Product Description
The WOODWARD 9907-1200 is a CPC-II electro-hydraulic current-to-pressure converter designed for industrial steam turbine control systems. It converts a 4–20 mA DC electrical command signal into proportional hydraulic pressure to control single-acting steam turbine governor valve servos.
The unit provides precise hydraulic pressure regulation for turbine speed and load control applications. Its enhanced dynamic response supports accurate valve positioning during operating load changes.
The 9907-1200 features a 10-bar pressure range, simplex configuration, and Zone 2 hazardous-area classification. Its design incorporates hydraulic contamination resistance and a self-cleaning valve mechanism, making it suitable for demanding turbine control environments.
