Woodward 9907-1199 CPC-II Electro-Hydraulic Converter

The Woodward 9907-1199 CPC-II is an advanced electro-hydraulic interface device developed for turbine control systems.

It works as a bridge between modern electronic turbine controllers and hydraulic valve actuators. The converter receives an electrical demand signal from a governor or turbine control system and produces a proportional hydraulic pressure output to position steam control valves accurately.

The CPC-II design improves turbine control performance by providing stable pressure regulation, fast response during load changes, and enhanced tolerance against hydraulic oil contamination. It is commonly installed in steam turbines, turbo-generators, and industrial energy systems requiring precise valve positioning.
