Available in work ratings of 10.8 and 21.7 inch-pounds, the SG hydraulic speed-droop type governor is designed for use on small diesel, gas, or gasoline engines where isochronous control is not required. The droop control is such that the governor operates at a slower speed as engine load increases.
SG Simple Governors
Woodward’s SG and PSG governors are simple to operate and offer exceptional reliability. Driven by a suitable SG/PSG/EG drive on the engine, these governors operate using the engine’s own oil supply at minimum pressures of 25 psi.
Available in work ratings of 10.8 and 21.7 inch-pounds, the PSG governor is a pressure-compensated, speed-droop, or isochronous governor for controlling the speed of small diesel, gas, and gasoline engines, or small steam or industrial gas turbines. The governor is used to control engines or turbines driving alternators, DC generators, pumps, or compressors.
