- Manufacturer: Woodward
- Model/Part Number: D8516-051
- Description: TG-13 Mechanical-Hydraulic Speed Droop Governor, 4000–6000 RPM, 6050 RPM Rated Speed Droop at 2°, Counterclockwise Drive Shaft, 16 N·m (12 ft-lb) Output, for API611 Steam Turbines, ATEX Certified
Overview
- The Woodward D8516-051 is a TG-13 mechanical-hydraulic speed droop governor designed for API611 steam turbines driving pumps, compressors, or generators in applications where isochronous (constant-speed) operation is not required. It controls turbine speed by sensing rotor speed and adjusting inlet steam flow, providing a reliable and cost-effective solution for industrial power generation and mechanical drive systems.
