Woodward UG-25+ Electronic-Hydraulic Governor
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.
What does this mean for our customers?
The UG-25+ P3 is a fully compatible replacement product for all P0/P1 versions, which will be phased out of production on April 1, 2012. Service and repair support for P0/P1 versions will continue until January 1, 2014.
We recommend that customers upgrade their UG-25+ P0/P1 versions to the new P3 version at the next service overhaul. An upgrade program is offered through select Woodward Authorized Independent Service Facility (AISF) Business Partners, which are identified below as Certified Overhaul Partners. After this first service update, the UG-25+ governor can be serviced as usual at all AISF’s around the world.
For details on the UG-25+ P3 please see technical manual 26579.
UG-25+ P3 Actuator
The P3 actuator has a work output range of 25 to 31 ft-lb. For actuator details, please see technical manual 26580 and product specification 03386.

UG-25+ marine type approval certificates have been renewed and updated for the P3 version models. There is no functional difference between P0/P1 and P3 versions.
The table below shows the P3 item numbers that replace P0/P1 item numbers. For each P0/P1 part number there are two possible replacement part numbers of P3, indicating the position of the oil gauge on either the right or left side of the governor.
