Woodward UG-40

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

UG-8

All UG-40 governors have adjustable compensation. A pointer on the governor sets and indicates the amount of compensation.

Compensation allows isochronous speed control. Compensation is temporary. A needle valve sets the speed at which compensation is removed from the governor speed setting. Special damped ballheads and spring-driven drives are available for engines with rough governor drives.

Droop is available in UG-40 Governors to allow load sharing between multiple engines or power generation against an infinite bus.

UG-40s have internal, self-contained oil supplies. The governors provide 38° of output shaft travel. Recommended usable rotation is 2/3 of the maximum, or 25°.
