8516-050 | Woodward Turbine Governor for Steam Applications

Product Description

The Woodward 8516‑050 TG-13F is a precision mechanical-hydraulic turbine governor designed for small to mid-sized steam turbines driving pumps, compressors, or constant-speed generators. It delivers reliable speed regulation through a centrifugal sensing mechanism and hydraulic actuation, ensuring stable turbine operation under varying load conditions.

This governor features a clockwise (CW) output shaft providing up to 16 N·m torque, suitable for direct linkage to throttle or steam control valves. Moreover, it includes configurable speed droop, enabling accurate load sharing in parallel turbine applications.

Its compact, weatherproof housing with a self-contained oil sump makes it suitable for harsh industrial environments and outdoor installations. The 8516‑050 is widely used in API‑611 process turbines, providing dependable performance in industrial facilities, refineries, and chemical plants.
