Woodward 8251-019 EG-3P Actuator with External Drain
The Woodward 8251-019 is an EG-3P electro-hydraulic actuator used as part of an engine fuel/governing system. It converts an electrical control signal from the governor/speed-control system into mechanical movement to regulate engine fuel, thereby helping maintain the required engine speed and load response.

Function
The EG-3P actuator is installed between the electronic control/governor and the engine’s fuel-control mechanism. The control system commands the actuator according to engine speed/load requirements; the actuator then positions the fuel-control mechanism. This allows precise fuel adjustment for speed regulation, load changes and stable engine operation.
The external drain configuration provides a dedicated drain arrangement for the actuator’s hydraulic/oil circuit. The Deutsch 90-degree connector is part of the specified 8251-019 configuration.
