The high pressure steam enters the Pressure Reducing Station
as shown in the figure. The steam inlet pressure gauge and dial thermometer indicate the pressure and temperature respectively of the inlet steam. The steam pressure control valve reduces the pressure of the steam. The steam inlet isolation valve along with the outlet isolation valve is used to isolate the steam pressure control valve, whenever maintenance of the control valve is to be carried out. The steam bypass valve allows steam flow at reduced pressure to continue when the steam pressure control valve is under maintenance or becomes inoperable. The pressure transmitter senses the outlet steam pressure and gives a proportional current signal as output to the PID controller. The PID controller then compares the measured value with a set point, and generates an error signal, which is then given to the positioner of the steam pressure control valve. The safety valve opens and relieves excess pressure when steam pressure goes above set value, and re-closes and prevents the further release of fluid after normal conditions have been restored.
