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 survive the competitive environment. A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. Reduced flow and excessive pressure drop are some of the common problems in ball valve. Angle backlash in the ball position is one of the causes for reduced flow and excessive pressure drop. This paper discusses on creating various alternatives for eliminating the angle backlash in the ball position, evaluating them and choosing the best alternative followed by CFD analysis of the ball valve before and after adjusting the backlash is made in ANSYS FLUENT and the results are compared.
