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.
Woodward PG dial governors control the speed of diesel, gas, and dual-fuel engines, including applications such as:
Besides controlling speed, PG governors can also limit load and shut down the engine when the lubricating oil pressure fails. Woodward customizes each PG governor to meet the needs of the engine and the application.
Woodward PG-200/PG-300 governors are designed to control speed and provide auxiliary PG limiting and control functions for large engines or turbines which require work capacity beyond the standard PG governor. With 237 or 422 J (175 or 311 ft-lb) of work capacity over 40° of output, the unit allows direct control of many engines without modification of the fuel system or use of auxiliary amplifiers.
Providing 648 J (478 lb-ft) maximum work capacity, the PG-500 governor is designed to control engine speed and provide auxiliary functions for very large engines or steam turbines.
Available optional features include:
The PGA is a pressure-compensated, hydraulic governor that uses an air signal to establish the engine speed setting of the governor.
The PGA features:
Similar to the PGA governor, the PGA-EG features mechanical ballhead backup for marine propulsion or other critical applications.
The PGG is a mechanical-hydraulic, pressure-compensated governor that can set speed or power output from a remote location. It combines a permanent-magnet, speed-setting motor for accurate remote speed adjustment with speed-droop adjustment and load-limit control features. Manual speed setting at the governor is also provided. Pressure-actuated or electric-solenoid shutdown is available, in addition to other PG auxiliary devices.
Similar to the PGG governor with remote speed setting capabilities, the PGA-EG features mechanical ballhead backup for marine propulsion or other critical applications..
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's work capacity ranges from 12-58 ft-lb (16-79 J).
