Abstract

This study has been performed to evaluate the safety of the retainer-type ball valve for a high-pressure pipeline to a district heating plant. The retainer-type ball valve is an improved design for conventional ball valves, such as the floating ball valve and the trunnion ball valve. Numerical analysis of the valve design verification has been applied to investigate the safety factor and seat leakage of the DN300 and DN400 sizes. The given condition to solve the structural analysis was based on the international standard for ISO 5208. In this study, the methods for structural analysis are described in detail. The structural analysis results present the deformations, the equivalent stresses, and the safety factors. Through these results, this study successfully demonstrates the safety and seat leakage of the retainer-type ball valve. They also streamline the process of development for valve manufacturing.
