Overview

The Woodward EGB‑13C Governor/Actuator is part of the EGB series (EGB‑10C, EGB‑13C, EGB‑35C, EGB‑50C). These governors are widely used in prime movers where both electronic and mechanical control are required. The actuator receives a 20–160 mA proportional signal from Woodward electronic controls, while the mechanical ballhead governor provides backup control if the electronic signal is lost.

This dual‑mode design makes the EGB‑13C highly reliable for critical industrial applications such as power generation, oil & gas, and marine propulsion.
