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.
Woodward hydraulic-mechanical governors provide reliable and precise control of engine speed and output in virtually every type of engine application. Woodward governors are used in power generation, marine, pump, compression, and vehicle applications. Available in work output ratings from 10.8 in-lbs up to 500 ft-lbs.
SG Simple Governors
UG Universal Governors
Woodward’s UG “universal” governors are mechanical-hydraulic governors for controlling diesel, gas, or dual fuel engines, or steam turbines. This proven design has been an industry standard for many years and worldwide acceptance provides easy service in most engine and governor shops.
UG governors have their own self-contained oil supply and are driven by a suitable UG drive from an engine or turbine. They operate either isochronously or in droop, and have a wide variety of optional features for use in generator, pump, marine propulsion, and other applications. UG governors have a maximum drive speed of 1500 to 1600 rpm.
The 3161 governor is a mechanical-hydraulic device that senses speed to control dual fuel engines, diesel engines, or steam turbines. The variety of standard features and available options make the governor ideal for a wide variety of applications that require work capacity of up to 24 N-m (18 lb-ft). Applications include off-highway vehicles, industrial, marine, generator set, compressor, or pump drives.
3161 operation can be isochronous for accurate constant speed or frequency control, or droop for load sharing. The amount of droop may be changed internally or with an optional external lever.
Among the governor options are torque rise and low idle offset which provide increased low speed, no load stability, and reduced undershoot and stalling.
The governor has its own sump for quick startup response. Direction of rotation of the governor drive is set at the factory, but can be changed in the field by turning the pump housing.
EGB Electronically Controlled Actuators with Mechanical Governor Backup
The mechanical governor backup capability of Woodward's EGB governor/actuators provides increased reliability and safety during the operation of dual-fuel and diesel engines or gas and steam turbines.
PG Large Pressure-Compensated Governors
Woodward's PG pressure-compensated governor line effectively controls the speed of the largest engines and turbines with work capacities ranging from 12 to 500 ft-lb (16 to 678 J). Choose the models from the list below that suit your applications.
