The SG governor hydraulic speed droop type governor is designed for use on small diesel, gas, or gasoline engines where isochronous control is not required. The design of the speed droop governor is such that the governor operates at a slower speed as engine load increases. It is through this characteristic that stability of the system is achieved and division of load between paralleled units is made possible.

The PSG governor is a pressure compensated, speed-droop or isochronous governor for controlling the speed of small diesel, gas, and gasoline engines, or small steam or industrial gas turbines. The governor is used to control engines or turbines driving alternators, dc generators, pumps, or compressors.

The UG governor is a mechanical-hydraulic governor 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. Proven design has been industry standard for nearly 50 years. World-wide acceptance provides easy service in most engine and governor shops. The UG governor drive configuration is the world-wide standard for many engine manufacturers

The PG-PL is a pressure compensated, isochronous control type governor widely used for controlling speed for all types of diesel or gas engines and steam turbines, driving pumps and compressors. It produces output in the 12 to 58 ft-lb range.

The EGB-10P, 13P, or 35P Governor/Actuator is used with Woodward analog or digital electronic controls that provide a proportional 20-160 mA signal to control dual fuel, diesel, and gasoline engines and gas and steam turbines driving electrical or mechanical loads. The governor/actuator provides 10, 13, or 35 ft-lbs (13.5, 17.62, or 47.46 J) work capacity to position fuel racks or linkage.

UG-40 governors are used for speed or load control of larger dual fuel, diesel, or gas engins 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.
