No. 50 – Steam System Process Control

1. STEAM PRESSURE CONTROLThe majority of industrial steam systems will have a pressure-reducing valve application. High-pressure steam is reduced to lower-pressure steam for a process or heating application. Used throughout all types of industries, some plants will have from one to over 100 different pressure control valves. The feedback control scheme is simply a pressure transmitter or a sensing line coming back to the valve.
