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).
