Woodward 8405-052 Hydraulic Actuator – Precision Control for Critical Power Systems

The Woodward 8405-052 hydraulic actuator is an industrial-grade electro-hydraulic positioning device engineered for demanding turbine control applications. This actuator provides reliable, high-precision modulation of fuel valves, steam admission valves, and guide vanes in gas turbines, steam turbines, and large-bore diesel engines used across power generation, marine propulsion, and oil & gas sectors.

Technical Specifications

  • Model Number: 8405-052
  • Actuator Type: Electro-hydraulic linear actuator
  • Control Signal: 4-20mA DC or 0-10V DC (configurable)
  • Operating Pressure: 1500-3000 PSI hydraulic supply
  • Stroke Length: Variable (application-dependent)
  • Response Time: <50ms for full stroke
  • Positioning Accuracy: ±0.5% of full scale
  • Operating Temperature: -40°C to +85°C
  • Enclosure Rating: IP65 (dust-tight, water-resistant)
  • Weight: Approximately 8 kg
  • Mounting: Standard flange interface with ISO compatibility

Key Features & Benefits

  • High-Speed Response: Sub-50ms actuation ensures rapid load changes and transient stability
  • Robust Construction: Corrosion-resistant materials withstand harsh industrial environments
  • Integrated Feedback: Built-in LVDT position sensor provides closed-loop control accuracy
  • Fail-Safe Design: Spring-return mechanism ensures safe valve positioning during power loss
  • Wide Compatibility: Interfaces seamlessly with Woodward governors and third-party control systems
  • Field-Proven Reliability: Decades of operational heritage in critical power applications worldwide

Application Scenarios

The Woodward 8405-052 actuator excels in:

  • Gas Turbine Power Plants: Fuel valve modulation for load control and emissions optimization
  • Combined Cycle Facilities: Steam admission control in heat recovery steam generators (HRSG)
  • Marine Propulsion: Governor control for ship diesel engines and auxiliary power units
  • Industrial Cogeneration: Precise steam flow regulation in CHP (combined heat and power) systems
  • Oil & Gas Compression: Speed and load control for gas turbine-driven compressors
  • Emergency Backup Generators: Fast-acting fuel control for rapid load acceptance

Integration & Control Solutions

This actuator integrates with Woodward control platforms including 505E, MicroNet TMR, and NetCon 5000 systems. It accepts standard analog control signals and provides position feedback for closed-loop governor operation. The unit can be configured for single-acting or double-acting hydraulic operation depending on valve requirements.

Common Questions & Answers

Q: What hydraulic fluid is recommended for the 8405-052?
A: Woodward recommends petroleum-based hydraulic oils meeting MIL-PRF-5606 or ISO VG 32-46 specifications. Synthetic fluids may be used in extreme temperature environments.

Q: Can this actuator replace older 8405 series models?
A: Yes, the 8405-052 maintains backward compatibility with legacy mounting interfaces and control signals, making retrofits straightforward with minimal system modifications.

Q: What is the typical service interval?
A: Routine inspection every 8,000 operating hours is recommended. Seal replacement intervals vary by application but typically range from 16,000-24,000 hours under normal conditions.

Q: Is calibration required after installation?
A: Initial calibration is performed at the factory. Field calibration may be needed to match specific valve characteristics—consult the installation manual for zero and span adjustment procedures.

Q: What warranty coverage is included?
A: All units ship with a comprehensive 12-month manufacturer warranty covering defects in materials and workmanship under normal operating conditions.
