description: This work is devoted to the development of a control valve, cellular with a rod plunger. Tasks that were solved during the work: 1. Study of the feedwater system BREST-OD-300 power unit. 2. Study of the types of fittings that are included in the feedwater system 3. Performance of strength calculation of the body of the developed valve. 4. Hydraulic calculation of the valves being developed. 5. Construction a profile of the plunger surface. Several sequential tasks were solved for the development of valves. According to the existing technical requirements, the housing of control valves was designed and strength calculation was carried out. As a result of the strength calculation of the housing, stable valve operation was established in various operating modes. The calculation was made in two ways: theoretical and numerical. The optimal profile of the plunger was determined by the method of curves of equal areas. Next, hydraulic calculation was carried out, which proved resistance to cavitation under various media supply modes. With the help of ANSYS software and SolidWorks CAD, the final model of the control valve for the feedwater system at the BREST-OD-300 power unit was developed.
