Responsive governor combines the best of electronic and hydraulic technologies for optimal engine operation.

The UG-25+ governor is a microprocessor-controlled, mechanical-hydraulic amplified governor for controlling diesel, gas and dual fuel engines, and steam turbines. The UG-25+ offers enhanced control capabilities, such as start fuel and boost limiting schemes. The additional transient fuel limiting (jump-rate) improves the engine load acceptance and reduces transient emissions significantly.

UG-25+ Features:

  • State-of-the-art speed sensing and control algorithms
  • Enhanced PID dynamics
  • Configurable speed settings and adjustment rates
  • Multiple fuel limiting algorithms, such as jump-rate, boost pressure, and start fuel limiting
  • Comprehensive diagnostics for easy troubleshooting
  • End-of-line programmability simplifies inventory

Next Generation UG-25+ P3

Since its introduction as a Woodward governor in 2006, we have driven continuous product improvements toward this next generation P3 version. In addition to enhanced performance in high-vibration environments, the P3 is also equipped with a new customer electrical interface.

Here's how the UG-25+ P3 benefits Woodward customers.

The UG-25+ P3 is a fully-compatible replacement product for all previous P0/P1 versions, which were phased out of production on April 1, 2012. We recommend that customers upgrade their UG-25+ P0/P1 versions to the new P3 version at the next service overhaul to gain the benefits of this improved P3 design (e.g., significantly increased service interval compared to the P0/P1 versions). Customers are also offered an option to get their P0/P1 versions serviced and repaired. These upgrade and repair programs are offered through Woodward Certified Overhaul Partners (see tab below). After this first update, the UG-25+ P3 governor can be serviced as usual at any Woodward Authorized Independent Service Facility (AISF) around the world.
