TG-13 8516-039 | Woodward Mechanical-Hydraulic Governor Module

Product Description

The Woodward 8516‑039 TG-13 is a high-precision mechanical-hydraulic turbine governor designed for small to mid-size API‑611 steam turbines. It provides accurate speed control for pumps, compressors, and constant-speed generator applications.

This compact, weatherproof governor features a self-contained oil sump and direct mechanical output shaft, making it suitable for harsh industrial environments and outdoor operation. Moreover, its robust construction ensures reliable turbine regulation under varying load conditions.

The 8516‑039 offers configurable speed droop and up to 16 N·m output torque, delivering dependable operation in both standalone and parallel turbine applications. Its counter-clockwise (CCW) output rotation integrates directly with throttle or steam control valve linkages, ensuring stable and precise turbine performance.
