Abstract
Valve is an important device which controls the flow rate, pressure, and flow direction. The selection of valves depends on the purpose, environment, and design of the usage. Because of the development of science and technology, the valve products become more accurate, so its performance and characteristic have already been the important research projects.
The objective of this paper is to study two different types of the ultra high purity valves. In the analysis of flow field, the velocity, pressure, temperature distribution and the valve flow coefficient (Cv) were studied in details with a CFD-RC code. In the stress analysis, the stress distribution and deformation of diaphragms which were oppressed by the mandrel when shutoff were discussed with a ANSYS code. The results can be used as the optimum design basis of the ultra high purity valve.
