Hi Guys
I'm working on one power plant we have GE 9FA gas turbine. I notice in the device summary for the servo valves GE tag number sometimes the start with 90 and some times start with 65.
like:
90SR-1 >> STOP/SPEED RATIO VALVE SERVO VALVE
and
65FP-1 >> LIQUID FUEL PUMP (BYPASS VALVE) SERVO VALVE
but in the field it looks same
so any body have idea what is the difference?
Thanks
