The Woodward UG40 Actuator replaces UG32 or UG40 type governors on engines and turbines, providing electronic control and load sharing capabilities with the existing UG40 drive and linkage. With 85 N·m (63 lb-ft) of work output, a 7.0-liter self-contained oil sump, and optional integrated MPU, the UG40 Actuator simplifies retrofit from mechanical to electronic governing.
