The PG-PL Governor is an isochronous pressure – compensating governor usually used in turbine applications with a wide range of servo outputs available.

The PG-PL Governor is widely used for controlling speed for all types of diesel or gas engines and steam turbines, driving pumps and compressors with a wide variety of pneumatic speed ranges available together with shutdown options.

Other options available consist of:
• Magnetic pick up facility
• Various base options
• Various driveshaft options
• Overspeed test device
• Lube oil or air shutdown facility
• Self-contained sump

The workload output of the PG-PL ranges from 12 to 58 ft-lb in the format of either linear or rotary output.
The main advantages of this governor are that it has a number of power options and can easily be adapted to fit many manufacturers’ prime movers.


PGDs (PG governors with dial speed setting) and PGLs (PG governors with lever speed setting) control the speed of diesel and dual fuel engines but are most frequently used on turbines. The PGD also facilitates the addition of speeder motors, shutdown and overspeed test device.

PGDs can be used with a variety of drive shaft options in addition to droop facility.


The PGA is much like the standard PG model , however with the inclusion of an air speed setting facility,it is used extensively in marine applications.
It is a pressure – compensated , hydraulic governor that uses an air signal to establish the engine speed setting of the governor.

Other PG’S within this range include the PG-200, the PG-300 and the PG-500.
