Woodward UG Universal Governors

    Mechanical-hydraulic governors for dependable control of engines or steam turbines

    Woodward’s UG “universal” governors are mechanical-hydraulic governors for controlling diesel, gas, or dual fuel engines, or steam turbines. This proven design has been an industry standard for many years and worldwide acceptance provides easy service in most engine and governor shops. 

    UG governors have their own self-contained oil supply and are driven by a suitable UG drive from an engine or turbine. They operate either isochronously or in droop, and have a wide variety of optional features for use in generator, pump, marine propulsion, and other applications. UG governors have a maximum drive speed of 1500 to 1600 rpm.


    UG-25+ Governors

    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-8 Governors

    The UG-5.7/8/10 governor is a mechanical-hydraulic governor for controlling diesel, gas, or dual fuel engines, or steam turbines. These governors (generally known as “UG-8”) are available in either a UG dial or UG lever configuration. UG dial governors are particularly suited for constant speed applications. UG lever governors are widely used for variable speed control.

    The UG-8PL is a compensated, isochronous governor for use with diesel, gas, and dual-fuel engines or steam and industrial gas turbines driving pumps, compressors, alternators, generators, etc. Either direct or reverse pneumatic speed setting mechanisms are commonly used with this governor.

    UG-40 Governors

    UG-40 governors are used for speed or load control of larger dual fuel, diesel, or gas engines or steam turbines, with governor drive speeds of 350 to 1050 or 550 to 1300 rpm. Governors with lever speed setting are primarily used for propulsion engines. Dial or motor speed setting is primarily used for power generation installations.

    UG MAS Governors

    The UG MAS (milliamp speed setting) controls the speed or power of prime movers used for propulsion, locomotives, pumps, and compressors. The pressure-compensated, hydraulic governor accepts a standard 4-20 mA electrical current signal to set the speed of the governor. An internal pump, relief valve, and accumulator system maintain the governor operating pressure. A self-contained sump stores the oil and reduces the possibility of contamination from outside sources.
