Optimization of 16" Plug Valve Body Using FEA And Experimental Stress Analysis Method
Abstract. In the field of competition, all companies should supply their goods and services with high quality, in shortest period with lower prices than its competitors in order to keep their capacity and power to compete .Plug valves are machine elements which are commonly used for regulation of fluid, semi liquid and granular medium flow on variety of tanks and pipeline systems. This paper discusses FEA analysis of P lug valve body followed by Experimental stress analysis using strain gauge method for weight optimization. New optimized models were prepared on the basis of validation of the results obtained from stress analys is procedure. The weight reduction is done by changing the wall and rib thickness. The results clearly shows the maximum weight reduction is 24.86 kg (5.26% weight of original weight while keeping maximum stress level up to 168.6 N/mm 2 which is safe for the applied load.
