WOODWARD
UG-8 Governor
The Woodward UG-8 Governor is a mechanical hydraulic governor for controlling diesel, gas, or dual fuel engines, or steam turbines.
UG Lever governors are widely used for variable speed control. Remote speed setting can be either mechanical through the speed setting lever or pneumatic with a special speed setting device. Special attachments are available for other applications.
This proven design has been industry standard for many years. World-wide acceptance provides easy service in most engine and governor shops.

SG/PSG
The SG/PSG governor provides hydraulic powered travel in the increase-fuel direction only. A return spring is used to provide travel in the decrease-fuel direction. The standard PSG cover provides for a vertical return spring in the governor. Governor models are available with horizontal return springs, or the governor can be fitted with a customer supplied external return spring.
Spring-driven and oil-damped ballheads are available to filter out torsional vibrations. A special temperature-compensated needle valve can be supplied to compensate for temperature effect on stability.

EPG
The EPG (Electric Powered Governor) is designed for precise speed control of diesel, gas, gasoline engines, and gas turbines. The governor is especially suited to prime movers without a mechanical drive or hydraulic oil supply for the governor and which have low-mass, low-friction fuel linkages. Controls are built with dynamics designed for specific engine applications.
Units with start fuel limit can prevent startup overspeed and excessive startup smoke.

EG3P Actuator
The EG-3P/6P/10P actuators convert an electrical signal to a proportional rotary output shaft position to control the flow of fuel or energy medium to a prime mover.
These actuators are suitable for controlling diesel and gas engines or steam and industrial-commercial gas turbines driving alternators, dc generators, pumps, compressors, papermaking machines, or locomotives. A Woodward hydraulic amplifier can provide larger work capacities.

TG13
TG Governors are self-contained, mechanical-hydraulic, speed-droop governors for use on small steam turbines driving pumps, compressors, or generators, where isochronous (constant speed) operation is not required. These governors are directly coupled to the steam-turbine’s rotor or auxiliary shaft to sense and control turbine speed.

PEAK 200
PEAK 150
The Woodward Peak 150® steam turbine control is a low-cost, compact, digital control for single-valve or single-valve rack steam turbines. It provides convenient operator control and speed display from the front panel. It is housed in a watertight, and dust-tight, enclosure. A corrosion-resistant enclosure designed to meet NEMA 4X requirements is also available.
PEAK 200
The Woodward Peak 200® controller is designed to operate small single valve, or single valve rack industrial steam turbines. This cost effective steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect small industrial steam turbines or turbo expanders driving compressors, pumps, or industrial fans.
The Peak 200 control’s unique PID structure makes it ideal for applications where it is required to control steam plant parameters like turbine speed, turbine load, turbine inlet header pressure, turbine exhaust header pressure, pump flow, or compressor discharge, or suction pressure.

Mechanical Governors
While many Caterpillar engines utilize advanced electronic control systems, with integrated engine speed governing capabilities, there are many Caterpillar engines, both gas and diesel, that require the use of separate engine speed governing systems. These Hydra-Mechanical governors are oil fed with rotating weights inside to control engine speed and adjust to load changes.
