Woodward UG-25+ Electronic-Hydraulic Governor

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

     UG-25 Plus P3

    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

            UG-25-P3-FINALNew-symbol-png   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.

    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

     

     

    These Woodward Certified Overhaul Partners can upgrade your UG-25+ P0/P1 to the new P3.

    After this upgrade, the UG-25+ P3 governor can be serviced at any Woodward Authorized Independent Service Facility (AISF) around the world.

    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.
