The Woodward PG-EG Actuator replaces PGA/PGG/PGE-type governors on diesel engines, providing electronic control advantages while retaining the existing PG-type drive and linkage. It converts an electrical input signal to a proportional hydraulic output shaft position, with a self-contained oil supply and drive speeds from 200 to 1,200 rpm. Recommended for installations involving unattended starts.
Key Features
