Woodward 8250-749 Fuel Control Actuator

Product Brief Introduction Electromechanical fuel actuator designed for large gas and diesel prime movers, converting control signal into mechanical shaft displacement to adjust fuel valve opening for speed governing.
Tag:

Technical Specifications 24VDC control power, compatible with standard governor drive signal. Operating temperature: -40℃ ~ +85℃.

Functional Features Precise linear stroke output; built-in position feedback; overload and stall protection; fail-safe minimum fuel position upon signal loss.

Application Scenarios CAT large gas engines G3508, G3512, G3516, stationary generator sets and industrial prime mover fuel regulation.

Performance Parameters High positioning repeatability, low hysteresis, stable continuous operation under high vibration engine environment.

Structural Characteristics Integrated metal sealed housing, internal coil and feedback transducer assembly, output drive shaft for mechanical linkage.

Working Principle Receive current command from governor controller, drive internal torque motor to rotate output shaft, built-in position sensor feeds actual stroke back to controller for closed-loop regulation.

Installation Requirements Mount directly on engine fuel rack, align linkage to eliminate side load, use anti-vibration mounting base.

Usage Notes Regularly inspect connecting rod wear; avoid mechanical binding of output shaft; check sealing for oil contamination.
