Study on characteristics and performance of butterfly valve using numerical methods - A review

A valve is a device that control or regulate the fluid in pipe line, which commonly used all industries like oil and gas, process, power, mining, etc. Valves are mainly classified into two types, namely, linear motion rotary motion. butterfly among family of (quarter turn valve) having metal closure plate along with middle shaft, acts as rotating axis. The quarter valves fast to open close they required only 90 degrees rotate order fully open. objective this paper identify study various characteristics performance process through literatures. most important key parameters identified such operating torque sealing hence additional research optimize by using finite element analysis engineering hand calculations. Also, it concluded size optimization best methodology for according industrial market scenario. In future research, factors influencing design variables be explored more scientific methods relationship between investigated find impact values changes technique regression analysis, correlation coefficient, variance etc., Further reverse carried out high explore performances same has been optimized calculation without affecting international guide lines.
