Woodward UG-8 Governors

    The industry standard for constant or variable speed control

    UG-8 Lever                      UG-8 Dial 

    The UG product s are mechanical-hydraulic governors for controlling diesel, gas, or dual fuel engines, or steam turbines. The governor provides extremely reliable speed control throughout the drive speed and temperature range. This proven design has been the industry standard for many years and its worldwide acceptance provides easy service in most engine and governor shops.

    UG governors (generally known as the “UG-8”) are available in either a UG Dial or UG Lever configuration. Each model is available with any of three different work outputs:

    UG-5.7: 7.1 N-m (5.2 lb-ft) / UG-8: 13.2 N-m (9.7 lb-ft) / UG-10:15.9 N-m (11.7 lb-ft)

    UG-Dial governors are particularly suited for constant speed applications. Knob speed settings make synchronization easy for generator applications. Motor speed setting is available for remote synchronization. Adjustable droop makes load sharing between engines precise.

    UG Lever governors are widely used for variable speed control. Remote speed setting can be either mechanical through the speed setting lever or pneumatic with a special speed setting device. Special attachments are available for other applications.

    The UG pump is designed for applications which reverse engine rotation.
