Fail-Safe: On power loss or external shutdown command, the driver cuts motor power and the internal spring returns the metering sleeve to minimum fuel position.
Application Scenarios: Industrial gas turbine fuel control; installations requiring no hydraulic oil source; explosive atmosphere zones (Zone 1/Division 1); DLE high-precision control; integration with Woodward NetCon and MicroNet systems; power generation, petrochemical, oil & gas transmission, and distributed energy.
Installation & Precautions: Identical to 8915-1152 — careful handling to preserve factory calibration, 25 µm absolute gas filtration, strictly controlled contaminant limits, shielded resolver wiring with proper grounding, torque-specified bolt tightening, and adherence to Woodward-recommended maintenance intervals.
Note: Exact flange class, port size, and certification variant of 8915-1165 require Woodward factory confirmation. The 3103/EM35 family is on Woodward’s obsolescence path with last-time-buy ending September 30, 2027; upgrade path is GS40/GS50 Series.
