Woodward 8256-022 Electrically Powered Governor
This actuator is the core component of the engine speed control system, and its main features include:
Fully Electric Drive: No mechanical drive or hydraulic power source is required, making installation extremely simple.
Low Power Consumption Design: Specifically designed for 12V DC systems (operating voltage range approximately 10–16 Vdc), with a maximum current consumption of approximately 4A.
High Response Speed: Capable of quickly adjusting the fuel pump or throttle for precise speed control.
Dual Output Shaft: Features a bidirectional output shaft design, increasing installation flexibility and allowing for either clockwise or counterclockwise fuel injection as needed.
Durability: Constructed from corrosion-resistant materials, enabling long-term operation in high temperatures (-40°C to 82°C) and harsh engine compartment environments.
