WOODWARD 8915-2007: UG20 Actuator

The WOODWARD 8915-2007 is a key component in industrial control systems, primarily functioning as a mechanical actuator. It’s designed to precisely convert control signals into mechanical motion to regulate various industrial processes and equipment.

Product Overview

This part number designates a specific configuration of Woodward’s well-known UG20 Actuator series. UG20 actuators are electromechanical or hydraulic/pneumatic devices often used in conjunction with governors or other control systems to manage engine speed, turbine power, or other critical parameters.

• Product Type: Actuator
• Manufacturer: Woodward
• Part Number: 8915-2007
• Model Designation: UG20 Actuator
• Key Features (from catalog notes): This specific configuration includes “SERR T/S W/INDICATORS, PG ADAPTER, CSA”.
  • SERR T/S: Likely refers to a serrated output shaft for secure linkage, and possibly “T/S” indicates a specific type of feedback or control.
  • W/INDICATORS: Suggests it includes visual indicators for position or status.
  • PG ADAPTER: Indicates compatibility with a pressure gauge adapter.
  • CSA: Certified by the Canadian Standards Association, meaning it meets relevant safety and performance standards for use in Canada and often other North American markets.
• Function: Converts control signals (often from a governor or control module) into precise mechanical action to operate fuel racks, valve linkages, or other control surfaces on prime movers (engines, turbines) or industrial machinery.

Detailed Product Description

The Woodward UG20 Actuator series is renowned for its robust design and reliable operation in demanding industrial environments. While detailed public datasheets for every specific part number like 8915-2007 are not always readily available, the general characteristics of the UG20 series apply:

• Electromechanical or Hydraulic/Pneumatic Operation: UG20 actuators can operate using either an electrical input (for electromechanical versions) or hydraulic/pneumatic pressure, depending on the specific model and application.
• Precision Control: They provide highly accurate and repeatable positioning, crucial for maintaining stable operation of engines and turbines.
• Robust Construction: Built to withstand harsh industrial conditions, including vibrations, temperature fluctuations, and continuous duty cycles.
• Feedback Capability: Many UG20 actuators include integrated position feedback mechanisms, allowing the control system to monitor the actual position of the actuator for closed-loop control.
• Versatile Applications: Designed for a wide range of prime movers and industrial machinery where precise control of fuel, air, or other parameters is essential.
