How would you control pressure, temperature and flow in the inlet and outlets, though? Would it be some kind of cascade control system?

[@Wadhar51]

Pressure/temp from upstream of the turbine process like vent/control valves while flow can be controlled with a lube oil governor valve, lp heaters are under vacuum

[@ferryfernando4303]

@@Wadhar51 what is the different between governor valve and control valve ? because sometimes governor and control valve is same

[@Kotabaru-xu3hg]

1. The governor valve's function is to regulate the flow of steam entering the turbine to match a predetermined set point. The governor valve calibration process is carried out before the generating unit start up process. 2. A control valve is a valve used to control fluid flow by varying the size of the flow path according to that directed by a signal from the controller, making it possible to directly control the flow rate and being an important control for several processes such as pressure, temperature...
