MADE IN FRANCE
The Nabco EAL-300 is a DC servo motor actuator designed for use within the Nabco MG800 governor system, a precision marine engine speed control and management solution. Manufactured by Parker SSD Parvex in France, this actuator serves as the electromechanical output stage of the governor system, converting electronic control signals into precise mechanical positioning to regulate fuel rack or throttle movement. As a core component within the Marine Control System category, it plays a critical role in maintaining stable engine speed under varying load conditions — directly supporting safe propulsion and auxiliary machinery operation onboard.
Key Features
✓ DC servo motor actuator (type MD17HSR0528) manufactured by Parker SSD Parvex, France, providing precise and responsive electromechanical actuation for governor control applications.
✓ Designed for integration within the Nabco MG800 governor system; compatibility with other controllers or panels is subject to confirmation based on vessel-specific configuration.
✓ Servo-driven design enables accurate and repeatable positioning, supporting stable engine speed regulation under dynamic load changes typical of marine operations.
✓ Mounting location and installation environment are dependent on engine room layout and governor panel arrangement; installation conditions should be confirmed against original system documentation.
✓ A direct replacement component for the EAL-300 actuator in MG800 governor systems, making it an important spare for scheduled maintenance and emergency servicing of engine speed control systems.
Marine Applications
✓ Main propulsion engine governor systems aboard cargo vessels, tankers, and bulk carriers requiring stable speed control under variable load.
✓ Auxiliary diesel generator governor control on offshore platforms, ferries, and naval support vessels where precise frequency regulation is essential.
✓ Tug and workboat engine management systems where rapid load response and actuator reliability are operationally critical.
✓ Passenger vessel and RoPax ferry propulsion control systems requiring consistent engine performance across varying sea states and operational profiles.
✓ Retrofit and overhaul projects on vessels with existing Nabco MG800 governor installations requiring like-for-like actuator replacement.
