A steam turbine for a combined gas and steam-turbine power plant process, including at least one valve arrangement for the controlled feeding of live steam into the steam turbine is disclosed. The valve arrangement has a quick-closing valve and at least one live-steam control valve assigned to the quick-closing valve. In addition, the steam turbine has a live-steam bypass, which, feeds live steam as "bypass steam" into the high-pressure region of the steam turbine through at least one bypass line and through a bypass feed assigned to each bypass line, but after the first turbine moving-blade row, as viewed downstream of the steam-turbine inlet region. At least one live-steam control valve and at least one bypass control valve are assigned to at least one quick-closing valve. Further, a method of feeding bypass steam into the steam turbine is disclosed.
