Optional Features

An oil cooler is recommended when governor oil temperature exceeds 99 °C (210 °F) or

governor drive shaft speed exceeds 1200 rpm on diesel or gas engines,

or 1100 rpm on steam turbines.

Air, oil, or water shutdown devices, either high or low pressure, are available for

engine protection. An energize or de-energize solenoid shutdown device is also

available.

For quick starts, a booster servomotor is available to supply immediate oil pressure

to the governor. This conserves engine starting air.

Preloaded buffer springs are available for governors used on gas engines and on

some engines driving reciprocating pumps.

Various base and power cylinder assemblies are available to conform to engine or

turbine manufacturer’s specifications.

Power servos may be mounted integrally on the governor with the terminal shaft in

either the 3. 6. 9. or 12 o’clock positions. Power servos also may be mounted

remotely from the governor. However, rotary power servos mount vertically only.
