description: This work is devoted to substantiating the possibility of using the RC 109.3.200 valve in the pressure reducing plant for utility needs for the BREST-OD-300 reactor. Tasks that were solved during the work: 1. Obtaining flow capacity of the valve at various opening angles. 2. Performing a numerical cavitation calculation of the valve. 3. Performing normative and numerical strength calculations of the lid and body of the valve. 4. Performing analytical and numerical strength calculations of the rack of the valve. Numerical calculations were performed using Ansys Fluent and Mechanical software. As the result of the work, the flow characteristic of the valve was obtained. In case of using the valve for regulating water, the cavitation onset Kc and critical flow Km coefficients were determined, as well as the maximum pressure drop, at which the cavitation-free mode is maintained. As the result of the strength calculation, it was shown that the strength conditions were fulfilled both according to the normative methodology and numerically.
