Applications

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.

Standard Features

An internal oil pump, relief-valve, and accumulator system controls governor

operating pressure. A self-contained sump stores oil and reduces contamination from

outside sources.

Oil flow to and from the governor cylinder assembly is controlled by a centrifugal

flyweight-head and pilot-valve assembly. A power cylinder (servomotor) positions

the fuel racks, fuel valve, or steam valve of the engine or turbine.

A pneumatic (direct or reverse) operated bellows-type mechanism sets governor speed.

A knob on the governor provides a means of manual speed adjustment.

Governor stability is provided by an adjustable needle valve and spring-loaded

buffer compensation system.
