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.

The TG Governors are self-contained mechanical-hydraulic speed droop governors for use on small steam turbines where isochronous (constant speed) operation is not required.

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.
