Description
Woodward TG-138516-038
Technical Specifications
- Part Number: 8516-038.
- Base Model: TG-13 Mechanical-Hydraulic Governor.
- Oil System: Self-contained.
Functional Features
- Custom Calibration: Factory-set to match the specific steam valve characteristics and turbine inertia of the host equipment.
- Droop Control: Provides stable, non-isochronous speed regulation.
- Direct Replacement: Designed as an exact mechanical and functional fit for the specified OEM application.
Application Scenarios
Used as a direct replacement or upgrade for small steam turbines originally equipped with the 8516-038 specification governor.
Performance Parameters
- Max Rotation: 40 degrees.
- Recommended Stroke: 2/3 of full travel from no-load to full-load.
Material Composition
OEM-specified materials ensuring compatibility with original steam valve linkages and operating environments.
Structural Characteristics
- Exact Footprint: Matches the dimensional envelope of the original 8516-038 unit.
- Integrated Components: Self-contained oil reservoir and hydraulic servomechanism.
Working Principle
Converts mechanical speed deviations into hydraulic pressure changes to actuate the turbine steam valve. The internal spring and flyweight assembly are calibrated specifically for the 8516-038 performance curve.
Installation Requirements
Verify the part number 8516-038 matches the turbine’s specification plate before installation. Reuse or replace linkage hardware according to OEM torque specifications.
Precautions for Use
Do not interchange with other TG-13 part numbers without verifying calibration compatibility. Always perform a no-load and full-load stroke test after installation.
