The Woodward ProAct Digital Plus 8404-010 is a high-performance electrical actuator with an integrated driver module, designed to deliver precise fuel control and speed governing in marine diesel and gas engine applications. As a core component within a vessel’s marine control system, this actuator translates electronic control signals into accurate mechanical output, directly governing engine fuel rack or throttle position. Its integral driver design consolidates electronics and actuation into a single unit, reducing wiring complexity and improving response reliability — factors that are operationally critical for maintaining stable engine speed, load sharing, and emissions compliance at sea.
Key Features
✓ Electrical actuator with integral driver electronics, enabling direct interface with Woodward ProAct Digital Plus governor control systems without a separate driver module.
✓ Specific voltage, current, and response time ratings are subject to confirmation based on nameplate data and system configuration — buyers should verify compatibility against their existing governor setup.
✓ Designed for compatibility with Woodward ProAct Digital Plus governor controllers; integration with other control platforms should be confirmed prior to installation.
✓ Suitable for mounting directly on engine fuel control linkages in engine room environments; installation context and environmental ratings should be verified against vessel-specific requirements.
✓ Replacement of this actuator typically requires calibration and commissioning by a qualified marine engineer or Woodward-authorised service technician to ensure correct governor response and engine protection.
Marine Applications
✓ Main propulsion diesel engine governor control on commercial cargo vessels, tankers, and bulk carriers requiring precise speed and load regulation.
✓ Auxiliary engine and generator sets onboard where stable frequency and load control are essential for vessel power management systems.
✓ Dual-fuel and gas engine control applications where accurate actuator response is required to manage fuel admission and combustion stability.
✓ Retrofit and upgrade projects replacing older mechanical or analogue actuator assemblies with digital governor control technology on existing vessels.
✓ Offshore support vessels, ferries, and RoPax vessels where reliable engine response is critical to dynamic positioning, manoeuvring, and passenger safety operations.
Why Marine Engineers Choose
The Woodward ProAct Digital Plus platform is widely trusted in the marine industry for its robust integration of actuation and driver electronics, reducing potential failure points and simplifying fault diagnosis. The 8404-010 variant offers a self-contained solution that supports accurate governor performance — a key requirement for engine protection, fuel efficiency, and regulatory compliance on working vessels.
Ideal For
Commercial cargo ships, bulk carriers, tankers, offshore support vessels, ferries, RoPax vessels, dredgers, and any vessel class operating Woodward ProAct Digital Plus governor systems on main or auxiliary diesel and gas engines.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, commissioning, and integration of this actuator within existing governor and engine control systems. Repair, bench testing, and retrofit guidance can be arranged subject to confirmation of scope and vessel requirements. To confirm compatibility and ensure correct supply, buyers are advised to share nameplate photographs, the full part number and revision, governor controller model and software version, engine make and type, existing wiring diagrams or installation drawings, and vessel name or IMO number where applicable. All compatibility and suitability assessments are subject to confirmation based on the information provided.
