The Woodward UG Governor (widely known as the UG-8) is an industry-standard mechanical-hydraulic governor for controlling diesel, gas, or dual fuel engines and steam turbines. With worldwide acceptance and decades of field-proven reliability, the UG provides extremely reliable speed control with isochronous or droop operation across the full drive speed and temperature range.
