WOODWARD 9907-018 Product Introduction
1. Product Overview
The WOODWARD 9907-018 is a precision industrial fuel control module designed for regulating fuel flow in engines, gas turbines, and diesel generators. It serves power generation, marine, oil & gas, and heavy-duty transportation industries—focusing on applications like diesel engine fuel metering, gas turbine fuel ratio control, and generator load-dependent fuel adjustment, which are critical for optimizing fuel efficiency and reducing emissions.
Integrating analog/digital control interfaces and robust fuel valve drivers, it adapts to dynamic load changes while withstanding harsh industrial conditions. Compatibility with Woodward speed controllers and standard sensors ensures seamless integration into existing power systems, making it a trusted choice for demanding fuel management tasks.

3. Product Specifications & Features
3.1 Core Specifications
The WOODWARD 9907-018 is optimized for multi-fuel systems, supporting diesel, natural gas, and HFO to fit diverse power equipment needs (e.g., marine diesel engines vs. natural gas turbines). Its ±1% fuel flow accuracy ensures precise metering, preventing over-fueling (which increases emissions) or under-fueling (which reduces power output).
The PWM output directly drives fuel control valves, while the 4–20 mA feedback signal enables closed-loop control—adjusting fuel flow in real time based on engine speed or load. RS485 communication allows remote parameter setting (e.g., fuel flow limits), reducing on-site maintenance time.
3.2 Key Features
- Multi-Fuel Support: Compatible with diesel, natural gas, and HFO, eliminating the need for separate modules for different fuel types.
- Precise Closed-Loop Control: ±1% accuracy and real-time feedback optimize fuel efficiency and reduce emissions.
- Harsh Environment Resilience: IP65 enclosure and -40°C to +70°C operating range handle extreme temperatures, dust, and water splashes (e.g., offshore rigs, mining equipment).
- Marine-Grade Compliance: ABS/DNV GL certifications make it suitable for shipboard engines, meeting strict maritime safety standards.
- Easy Integration: Works with Woodward speed controllers (e.g., 8270 series) and standard sensors, simplifying system setup.
4. Other WOODWARD Fuel Control Products
