Abstract: This research examines equivalent stress and strain distribution in hermetic elements of an enhanced gate valve, focusing on wear effects and material properties. A novel computational framework for trapezoidal cross-sectioned sealing components was developed in MATLAB, integrating fuzzy logic and the "bee colony" optimization method to refine pressure distribution analysis. Finite element analysis and simulations enhance the reliability of valve hermetic elements under varying conditions. Key findings include equations governing stress and deformation in sealing components, considering structural and technological parameters. The study identifies 62 degrees as the optimal angular displacement for the trapezoidal hermetic element, minimizing wear and ensuring efficient sealing. Material interactions, such as ST20X-ST20X and ST40X-ST20X, were analyzed to assess wear behavior. Harder materials exhibited greater resistance but increased persistent wear. Advanced parametric analysis and 3D visualization establish a structured methodology for optimizing valve design. The results contribute to improving high-pressure valve applications through refined material selection, structural geometry, and sealing configurations. This research enhances valve technology and serves as a foundation for future innovations in industrial valve performance optimization.
