Validation of Valve Coefficients Using Experimentation and Numerical Analysis

Today's demanding projects calls for a quality valve that is effective in controlling the flow closed conduit with optimum velocity and least energy losses system. Proper selection of requires information on maximum minimum flows head loss wide range applications. Hence comprehensive research study was carried out an improvised tricentric butterfly 100 mm NB over conventional type globe at different percentages openings to determine performance characteristics CWPRS, Pune. These studies highlight improved valve. The findings exhibit exceptional advantage equal percentage control loop new S-shape characteristic curve linear has demonstrated opening between 15° 75° showing characteristic. minimal pressure drop these valves, causes significant savings broad applications like water distribution systems, power generation, refineries, chemical, desalination. validation by experimental data CFD obtained reasonable near-optimum results coefficients.
