PG Actuators & Governors

PG-PL Speed Control Governor is applied to all types of diesel/gas engines and steam turbines driving pumps and

compressors. Besides controlling speed, PG-PL governors can also limit load and shut down the engine when the lubricating oil pressure fails. Woodward customizes each PG-PL governor to meet the needs of the turbine or engine and the application.

3161 Governors

The 3161 governor is a mechanical-hydraulic device that senses the 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.

TG Actuators & Governors

TG-13E/TG-17E self-contained electro-hydraulic actuators are used in the replacement of TG

governors with an actuator and electric control system. The TG-13E and 17E proportional electro-hydraulic actuators convert an electrical signal to a corresponding proportional output shaft position in order to position the valve that controls the flow of steam (or energy medium) to the turbine.

Frequently Asked Questions

  • Ideally, an overhaul of a governor is recommended at the time of prime mover overhaul schedule or after 20,000 to 24,000 hours of service.

  • It depends upon the availability of spare parts. Usually, it takes 2-3 weeks or a maximum 7-8 weeks.

  • It depends upon the failures of internal mechanical spare parts. That's why we provide initially only the service charge quote. Once we receive the unit from the end-user then we disassemble the unit in our workshop, we do an assessment of internal parts/worn out percentage etc., and accordingly we provide the total cost of the overhaul, which includes service and cost of required spare parts.

  • Yes, we can supply complete units within minimum lead time.

  • Our warranty covers six months for workmanship and one year for spare parts supplied and installed by us, provided the overhauled unit is run with prescribed oil quality/quantity and the governor is not subjected to improper handling or abnormal operation.
