The present paper provides a CFD (Computational Fluid Dynamics) type analysis on a fluid flow through an hydraulic resistance with cylindrical slide and 4 orifices sleeve. Its purpose is to determine the optimal geometric configuration for this type of hydraulic resistances, in order to enhance the dynamic characteristics of control devices. The issues under study were velocity fiel’s distribution, aiming the velocity vectors orientation angle in the narrowest area, the flow regime, by determining the Reynolds number’s numerical value and the pressure field’s distribution, the analysis showing a sharp pressure drop due to the flow sections’s variation. Also, given the sudden pressure drop, it was necessary to highlight the areas where cavitation may occur.
