In this research, conducted by Dr. Önur GÖK and colleagues with the contributions and collaboration of ARKOC Valve, a comparative numerical analysis of a butterfly valve was performed to simulate the fluid flow inside the pipe. Within the scope of the study, the performance of a single disc butterfly valve flow in the opening process was examined. Since unsteady flow can be better understood well by examining velocity and pressure changes, velocity and pressure distributions were observed by studying the flow separation in the turbulent state, and vortex formations were also taken into account. In addition, an optimization study was carried out to reduce the operational coefficient values. As a result of the study, characteristic parameters such as flow coefficient, drag coefficient, and dynamic torque of conventional and optimized valves were compared. In order to evaluate the performance of the valves, the changes of the characteristic parameters at different opening angles were shown in tables and graphs. The results revealed that the butterfly valve affected the flow coefficients and the values were quite high. Therefore, an optimization that would reduce the coefficients at various operating angles was carried out on the valve disc. The average inlet pressure, drag and flow coefficients, and torque values were improved. The valve structure was optimized and lighter flow equipment was designed. The optimized butterfly valve was manufactured and tested. The results are satisfactory.
