Globe valves are primarily manufactured by a casting process are extensively used for controlling the fluid flow in pipelines in various mechanical devices, viz. boilers, condensers, overhead tanks, etc. However, the component faces a lot rejection due to various casting defects occurring during the manufacturing process majorly because of the improper gating system design. In view of this, the present work proposes a numerical simulation on globe valves prepared by the sand casting process by varying the number of gates in gating system design. The effectiveness of both the designs is evaluated in terms of flow front, air entrapment and porosity percentages obtained from both the designs. From the simulation results, it is observed that an increasing number of gates in gating system design can result in better flow front, lesser air entrapment, promotion of directional solidification and lesser porosity percentage in casted product. The proposed model can be useful for producing sound casted product and defect-free casting thereby reducing the manufacturing costs. © 2021, Springer Nature Singapore Pte Ltd.
