UG-40 mechanical governors provide larger speed turbine speed or load control. Lever speed setting options are primarily for propulsion engines. Steam turbine applications utilize governor drive speeds of 350 to 1050, or 550 to 1300 rpm. Dial or motor speed setting is primarily used for power generation installations.
All UG-40 governors have adjustable compensation. A pointer on the governor sets and indicates the amount of compensation. Compensation allows isochronous speed control.
