The 3D design of a pipe with two flanges and a square valve presents a functional and robust assembly ideal for fluid control in industrial piping systems. The straight pipe section is flanged on both ends, allowing secure bolted connections, while the centrally mounted square valve offers a compact, easy-to-operate control mechanism—often used for quick shutoff or directional flow management. The square valve design provides a distinct visual and mechanical interface, enhancing usability in tight or structured layouts. This configuration is widely used in sectors such as water treatment, HVAC, and chemical processing for its reliability, ease of maintenance, and modularity.
