What are the two main problems using the valves?

The two main problems with using valves are leakage and wear. Leakage can occur due to improper sealing or degradation of materials, leading to reduced efficiency and potential safety hazards. Wear, on the other hand, results from repeated operation and can cause malfunctions or failure, necessitating maintenance or replacement. Both issues can significantly impact the reliability and performance of systems that rely on valves.
