WOODWARD 5466-258 | Control valve actuator

1. Model Positioning and Core Function

• Series Affiliation:
  It belongs to Woodward's family of fuel control components, specifically designed for regulating fuel flow in internal combustion engines, gas turbines, and other power equipment. The 5466 series is typically associated with electro-hydraulic or electromechanical actuators that convert electrical control signals into precise mechanical movements to adjust fuel valves.
• Primary Purpose:
  As a fuel valve actuator, its core function is to receive electrical control signals (e.g., 4-20mA or 0-10V) from a master controller (such as a engine control unit or turbine governor) and actuate the fuel control valve accordingly. This ensures precise regulation of fuel supply, directly influencing engine/turbine speed, power output, and emissions performance.

3. Key Features

• Precision Control: Utilizes feedback mechanisms to maintain accurate valve positioning, ensuring stable fuel flow even under varying operating conditions (e.g., temperature fluctuations, vibration).
• Durability: Constructed with rugged materials (e.g., corrosion-resistant alloys) to withstand exposure to fuel vapors, oils, and extreme temperatures in engine environments.
• Fail-Safe Design: May include failsafe features (e.g., spring-return to closed position) to shut off fuel flow in case of power loss, enhancing operational safety.
• Compatibility: Designed to interface with Woodward's governors (e.g., 2301A, 2301D) and other industry-standard control systems, supporting seamless integration into existing setups.

4. Application Scenarios

• Industrial Engines: Used in diesel or gas engines for power generation, marine propulsion, or heavy machinery to regulate fuel delivery and maintain stable speed under variable loads.
• Gas Turbines: Applied in small to medium-sized gas turbines for CHP (combined heat and power) systems, ensuring optimal fuel-air mixture and efficient combustion.
• Critical Power Systems: Deployed in backup generators or emergency power units where reliable fuel control is essential for uninterrupted operation.

5. Documentation and Verification

• Official Datasheet: Detailed specifications (e.g., exact voltage ratings, torque output, mounting dimensions) are available in Woodward's technical documentation. Users can request the 5466-258 datasheet through Woodward's official website or authorized distributors.
• Cross-Reference: The model may be a variant of the 5466 series, with "258" indicating specific configurations (e.g., voltage, mounting type, or feedback options).
