The stop valve is located upstream of the control valve with respect to the stream of the heating steam, and the stop valve and the control valve are each formed in the valve body of a main valve thereof with a bypass valve for allowing the heating steam to flow therethrough. The arrangement enables steam to flow in a volume necessary for starting the steam turbine and allows the limitations placed on the stop valve in opening same to be eliminated.
