Woodward 9907-135 Driver Module – EG3P Electro-Hydraulic Governor Control System
When a driver module fails in a turbine or engine governor system, the consequences are immediate and severe: loss of speed control, uncontrolled acceleration or shutdown, and potential catastrophic equipment damage. In power generation, oil & gas, and marine propulsion environments, even minutes of unplanned downtime translate into tens of thousands of dollars in lost production. The Woodward 9907-135 Driver Module is the critical interface between the governor controller and the electro-hydraulic actuator — without it, the entire speed-governing loop is broken.
The 9907-135 is a purpose-built driver module within Woodward’s EG3P (Electro-Hydraulic Governor) control platform — one of the most widely deployed governor architectures in industrial turbines and reciprocating engines worldwide. Woodward has been the global benchmark for speed and load control since 1870, and the EG3P series remains a cornerstone of legacy and mid-generation plant infrastructure across North America, Europe, Southeast Asia, and the Middle East. This module occupies a precision role: converting low-level control signals into the high-current drive output required to position hydraulic actuators with millisecond-level response.
