At steam extraction and admission locations, steam flow control valves usually add to the steam and control system cost. When the steam is expanded through a high-pressure ratio, as in large steam turbines, the steam can begin to condense in the turbine when the temperature of the steam drops below the saturation temperature at that pressure.
