Abstract
The invention relates to a steam turbine comprising a valve arrangement for regulating the admission of live steam into the turbine consisting of two serially connected regulating valves. The two regulating valves enable a step-by-step separation of the live steam and ensure operational security in the case of a partial load operation of the turbine. Said valve arrangement is particularly suitable for steam turbines devoid of regulating steps in a fixed-pressure operation mode.
