Woodward 8516-038 TG-13 Turbine Governor
- Manufacturer: Woodward
- Model/Part Number: 8516-038
- Description: TG-13 Mechanical-Hydraulic Speed Droop Governor, 1200–2400 RPM, 2010 RPM Rated Speed Droop at 2°, Counterclockwise Drive Shaft, 16 N·m (12 ft-lb) Output, for API611 Steam Turbines
Overview
- The Woodward 8516-038 is a TG-13 mechanical-hydraulic speed droop governor designed for API611 steam turbines driving pumps, compressors, or generators where isochronous (constant-speed) operation is not required. It controls turbine speed by sensing rotor speed and adjusting inlet steam flow, offering a cost-effective, robust solution for industrial applications in power generation and mechanical drives.
