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

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