Woodward Actuators with Mechanical Backup
EGB family of proportional electro-hydraulic actuators
The mechanical governor backup capability of Woodward's EGB governor/actuators provides increased reliability and safety during the operation of dual-fuel and diesel engines or gas and steam turbines.
During normal operation, the electronic control and actuator section of the EGB regulates fuel to the prime mover. Upon loss of electronic control signal, the standard EGB is adjusted to cause prime mover shutdown. An electronic, pneumatic, or manual starting device is then used to allow prime mover starting and operation under ballhead control.
EGB models cover work capacities ranging from 1-300 ft-lb (1.4-407 J). Choose the unit from the list below that suits your particular application.
EGB-1P and EGB-2P
The EGB-1P and EGB-2P, like all EGB products, are proportional electro-hydraulic actuators with a mechanical backup governor. As such, they are particularly well-suited to engines operating in tandem to drive a common load. When paired with Woodward’s 2301 electronic control, a complete governing system is achievable.
Work capacity: 1 and 2 ft-lb (1.4 and 2.7 J)

EG-3P / EG-6P / EG-10P
These EGB governor/actuators provide the muscle for a Woodward 2301A, 723PLUS, or similar integrating electric control system.
Work capacity: 4.5, 6, or 10 ft-lb (6, 8, or 14 J)
