    • Corrosion can significantly affect the fatigue life of materials. Materials with good corrosion resistance are generally more durable in corrosive environments and may exhibit better fatigue resistance.
  10. Dynamic Simulation and Analysis:
    • Advanced engineering tools, such as finite element analysis (FEA) and dynamic simulation, can be employed to model and analyze the response of valve components to vibrations. This allows for the optimization of design and material selection.

It’s important for valve manufacturers and engineers to consider these factors during the design and material selection process to ensure that dual-plate check valves exhibit satisfactory performance under vibration and fatigue conditions. Regular inspections, monitoring, and adherence to industry standards can also contribute to the long-term reliability of valves in butterfly valve applications subjected to dynamic loading.
