WOODWARD E8250-502 GOVERNOR ACTUATOR

WOODWARD E8250-502 is a 24VDC electromechanical governor actuator for marine diesel engines and generator sets, belonging to Woodward 8250 series linear actuators, used to control fuel rack position of mechanical fuel injection pumps. The governor actuator converts electrical speed control signals from Woodward governor controllers into linear mechanical displacement, adjusting fuel rack to regulate engine fuel supply, achieving stable engine speed control under variable load conditions. The governor actuator integrates built-in position feedback sensor, feeding real-time fuel rack position signal back to governor controller for closed-loop precise positioning. The governor actuator accepts 4–20mA or pulse control command from speed controller, and provides mechanical stop limit for fuel rack travel. The governor actuator has internal fault detection for coil and position sensor circuit, supporting diagnostic signals to engine monitoring alarm system.

WOODWARD E8250-502 adopts heavy-duty metal sealed housing for engine room mounting. The electromechanical actuator has high force output to overcome friction of fuel rack under vibration environment. The electromechanical actuator can withstand high temperature, vibration and humidity in marine engine room environments, complying with marine classification requirements for continuous engine operation. The electromechanical actuator features manual override function for local inspection and emergency operation during overhaul. The electromechanical actuator has low maintenance design and long service life for marine main propulsion and auxiliary genset governor systems.

WOODWARD E8250-502 is widely deployed on cargo ships, tankers and offshore vessels equipped with medium-speed marine diesel engines for propulsion and generator speed governing control systems. The industrial spare part can replace defective actuators to restore fuel rack actuation, closed-loop position feedback and engine speed regulation rapidly. The industrial spare part matches original mechanical and electrical specifications for direct replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces vessel downtime during governor system overhaul and preventive maintenance.
