3 Operating Conditions
3.1 The maximum stroke of servomotor is compatible with the full opening of the guide blade. For medium, small and extra-small governors, the actual maximum opening of the guide blade shall correspond to at least 80% of the maximum stroke of the servomotor. The governor is consistent with the selected operating capacity of the oil pressure device.
