1. Product Title

WOODWARD 8516-180 – TG611-13 Mechanical Hydraulic Turbine Governor

2. Product Overview

The WOODWARD 8516-180 is a mechanical-hydraulic turbine governor designed for precise speed regulation in industrial turbine and engine control systems. Developed by Woodward, this model belongs to the TG611 series of governors widely used in industrial power generation and rotating machinery applications.

The WOODWARD 8516-180 is configured as a screw-type governor designed for 4000 RPM operation with clockwise rotation, providing stable speed control for turbines and engines operating under dynamic load conditions. The governor regulates the turbine inlet valve or fuel control mechanism by adjusting mechanical output in response to speed variations. It also includes ATEX compliance for operation in hazardous environments and incorporates overspeed testing capability for safety verification. This makes the WOODWARD 8516-180 suitable for critical applications where reliable turbine speed control and mechanical robustness are required.
