The flow in the unloading system of the control valve is modelled. Values of the flow coefficient for various slot widths and openings are evaluated. The changes of pressure in the spaces of the valve are recorded when the performance of the turbine is regulated and its impacts on the level of the stabilizing power at the given setting of the cone lift are evaluated. The results from experiments on the air model of the system are compared with the pressures measured on the model of the valve. The operational characteristics of the experimental steam turbine is considered.
