With over a century of mechanical governor experience, it’s no wonder that Woodward is the preeminent name among governor manufacturers. Our governors hold an extensive pedigree that dates back to 1870, starting with the enhanced waterwheel governor invented by our founder, Amos Woodward. By the turn of the century his son, Elmer, owned the patent on the first successful mechanical compensating governor for hydraulic turbines. Since then, we’ve been leveraging those basic mechanical governor principles into the world’s best mechanical and electronic governors for power generation, marine, pump, compression, and vehicle applications.
The API611 steam turbine controller designed for small single valve/single valve rack industrial steam turbines. The cost effective configurable controller includes specifically designed algorithms and logic to start, stop, control, and protect small industrial steam turbines or turboexpanders driving compressors, pumps, or industrial fans. The Woodward L-Series Speed Control is a microprocessor-based engine speed controller with built in Actuator in a small package. The L-Series can easily be programmed to match the operating parameters of every engine you produce.

Woodward also provides global support through an extensive network of AISFs (Authorized Independent Service Facilities) that have been trained by Woodward to support governors in every corner of the world. Many of these AISFs also have the engineering capability to provide upgrade to an electronic control for enhanced control capabilities.
