Mechanical Governors for Gas Engines

Engine manufacturers and users depend on Woodward hydraulic-mechanical governors to provide reliable and precise control of engine speed and output in virtually every type of engine application. Available in work output ratings from 10.8 inch-pounds up to 500 foot-pounds, Woodward governors are used in power generation, marine, pump, compression, and vehicle applications.




3161 Mechanical-Hydraulic Governor

The Woodward 3161 mechanical-hydraulic governor is designed for speed control of diesel engines, gas engines, or steam turbines. The variety of standard features and available options makes the governor ideal for use in a wide variety of applications which require work capacity of up to 24 Nxm (18 lb-ft). Applications include off-highway vehicles, industrial, marine, generator set, compressor, or pump drives.



EG-3P (proportional) & EG-3PC (proportional with compensation)

The Woodward EG-3P (proportional) and EG-3PC (proportional with compensation)actuators are designed for use on diesel, gas, and gasoline engines, or turbines, and are particularly well suited for use in control systems requiring a proportional mechanical output of a proportional electrical input.




PG-PL

The Woodward PG-PL is a pressure compensated, isochronous control type governor widely used for controlling speed for all types of diesel or gas engines and steam turbines, driving pumps and compressors. It produces output in the 12 to 58 ft-lb range.



PSG Governor

The Woodward 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.



SG Governor

The Woodward SG governor hydraulic speed-droop type governor is designed for use on small diesel, gas, or gasoline engines where isochronous control is not required. The governor operates at a slower speed as engine load increases achieving system stability and load division between paralleled units.



UG-25+ Governor

The Woodward UG-25+ governor is a microprocessor-controlled, mechanical-hydraulic amplified, governor for controlling diesel, gas, and dual fuel engines, and steam turbines. The UG-25+ offers enhanced control capabilities, such as start fuel and boost limiting schemes. The additional transient fuel limiting (jump-rate) improves the engine load acceptance and reduces transient emissions significantly. The UG-25+ concept offers a fast-acting and high-work-output governor, without the need for any auxiliary devices such as a start booster.
