Abstract
Steam turbines with or without a control stage are constructed with the same number of control valves. There are preferably two control valves in each case. The valve subassembly, the turbine outer casing and parts of the turbine inner casing are of identical design and can be used for steam turbines with or without a control stage. In the case of the steam turbine illustrated with a control stage, the inner casing is provided with integrated nozzle boxes, which are separated from each other by intermediate walls. In the case of a steam turbine without a control stage, the nozzle boxes, and accordingly, also the intermediate walls are missing.
