A Review of Finite Element Analysis methods of Butterfly Valves

Butterfly valves are machine elements which are commonly used for regulation of fluid, semiliquid and granular medium flow on variety of tanks and pipeline systems. Valves are widely used in various industrial branches, especially in power plant pipeline installations, transport systems for materials. The valves can be made of carbon and alloyed steel, grey or alloyed cast iron and of other plastic or rubber materials. This paper discusses FEA analysis of Butterfly valve body and weight optimization. The weight reduction is done by changing the disc thickness.
