The PG-PL governor
The 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.
PG-PL Product specificationThe UG-25+ governor
The UG-25+ governor is a microprocessor-controlled, -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 offer a fast-acting and high-work-output governor, without the need for any auxiliary devices such as a start booster.
UG-25+ Product specificationThe EGB Governor/Actuator
The EGB Governor/Actuator is used with Woodward analog or digital electronic controls that provide a proportional 20–160 mA signal to control dual fuel, diesel, and gasoline engines, and gas and steam turbines driving electrical or loads. The governor/actuator is available for outputs of 1, 2, 10, 13, 29, 35, 58, 200, and 300 ft-lb (1.4, 2.7, 14, 18, 39, 47, 79, 271, and 407 J) work capacity to position fuel racks or linkage. During normal operation, the electronic control and actuator section of the EGB regulates fuel to the prime mover. Upon loss of electronic control signal, the standard EGB is adjusted to cause prime mover shutdown. An electronic, pneumatic, or manual starting device is then used to allow prime mover starting and operation under ball head control. The ball head section also regulates fuel if the control fails in such a manner as to call for maximum fuel. The EGB governor/ actuator can also be factory set to give maximum fuel (reverse action) on electronic control signal loss. The self-contained hydraulic oil supply makes the governor easy to maintain in almost any installation environment.
EGB Product specificationThe PSG governor
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.
PSG Product specificationThe SG governor
The 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 design of the speed droop governor is such that the governor operates at a lower speed as engine load increases. It is through this characteristic that stability of the system is achieved and division of load between paralleled units is made possible.
