Turbine Governors

Low Cost, Reliable, Accurate

Woodward’s patented and perfected industry standard and trusted self-contained, mechanical-hydraulic, speed droop governors continue to be the most widely used equipment on small steam turbines driving pumps, compressors, and generators, where isochronous (constant speed) operation is not required. These governors control turbine speed by sensing turbine rotor speed via their input drive shaft, comparing this speed to an internal speed set point, then using a rotary output terminal shaft connected to the turbine’s governor valve to control turbine inlet steam flow.
