Woodward 8256-021 EPG Actuator (Electronic Actuator) is a key executive component under the Woodward brand for controlling power machinery (such as engines, turbines, etc.). It mainly cooperates with governors to achieve precise regulation of fuel supply, valve opening, etc. The following are its core parameters：

  • Product Type: Electro-Hydraulic Actuator (EPG)

  • Application Scenarios: Fuel control or valve adjustment for diesel engines, gas engines, gas turbines, etc.

  • Power Requirements:

    • Operating Voltage: 24VDC (wide range compatible with 18-32VDC)

    • Peak Current: ≤5A (instantaneous start-up), Continuous Current: ≤1.5A

Performance Parameters
  1. Output Stroke and Thrust

  • Standard Stroke: 25mm, 50mm (optional, depending on model configuration)

  • Maximum Thrust: ≥5000N (ensuring stable operation under high load)

  • Stroke Accuracy: ±0.5% (within the full stroke range)

  • Response Characteristics

    • Operating Speed: 0-100% stroke response time ≤0.5 seconds (typical value)

    • Resolution: ≤0.1% (ensuring fine-tuning precision)

  • Control Signals

    • Input Control Signal: 4-20mA or 0-10V (analog quantity, matching governor output)

    • Feedback Signal: 4-20mA (position feedback, linearly corresponding to stroke position)

  • Operating Environment

    • Temperature Range: -40°C ~ +85°C (adapting to extreme industrial environments)

    • Humidity: 5-95%RH (no condensation)

    • Protection Class: IP65 (dustproof and waterproof, suitable for outdoor or harsh environment installation)

    • Vibration Resistance: 10-2000Hz, 10g acceleration (complying with industrial vibration standards)

    Structure and Interfaces

    • Material: The shell is made of cast aluminum (with anti-corrosion surface treatment), and the internal core components are stainless steel and high-strength alloys

    • Installation Method: Flange or bracket mounting (adapting to various mechanical structures)

    • Interface Type:

      • Electrical Interface: M12 circular connector (waterproof type)

      • Mechanical Connection: Connecting rods, rockers, etc., can be equipped to adapt to different controlled components

    Functional Features

    • Closed-Loop Control: Built-in position sensor to achieve stroke closed-loop feedback, ensuring control accuracy

    • Overload Protection: Equipped with overcurrent and overtemperature protection functions, automatically entering safe mode in case of failure

    • Compatibility: Directly compatible with Woodward 2301, 2301D and other series governors, supporting plug-and-play

    • Environmental Adaptability: Anti-electromagnetic interference (EMC compliant with EN 61000 standards), resistant to oil pollution, dust and other industrial environments

    Application Fields

    • Fuel rack control of generator sets (diesel/gas)

    • Load regulation of industrial engines

    • Fuel valve opening control of gas turbines

    • Auxiliary system regulation of large power machinery
