description: The work is devoted to the design of national hydraulic equipment for moving the control valve of a steam turbine and providing the necessary time for its moving. To achieve this goal: the main static characteristics of the hydraulic drive were obtained and the calculation of the main design parameters of the hydraulic cylinder and the proportional electrohydraulic control valve was performed depending on the parameters of the movement of the output link; the axial hydrodynamic force operating in the directional spool valve in the Ansys CFX software package was calculated; a mathematical model of the hydraulic drive was completed and the dynamic characteristics of the hydraulic drive were calculated in the computational package MathCAD. As part of import substitution, national analogues of foreign equipment were selected. The results of the work are: a schematic diagram of the hydraulic drive for controlling the turbine control valve; dependencies obtained as a result of studies of the influence of the parameters of the output link movement on the characteristics and parameters of the hydraulic drive; static and dynamic characteristics of the hydraulic drive; results of numerical modeling in Ansys CFX.
