About the Woodward UG-8 Governor
The Woodward UG-8 is a mechanical-hydraulic isochronous governor with an output torque of 8 lb-ft (10.8 Nm). It is designed for speed control of diesel engines, gas engines, and steam turbines. The UG-8 is widely fitted to main propulsion engines, auxiliary diesel generators, and emergency diesel generators aboard merchant vessels and offshore platforms. It operates on an oil pressure system self-contained within the governor housing, using a gear-type oil pump driven from the input drive shaft.
