True or False: In gate valves, the parts that usually sustain the most wear are the discs and seats.

In gate valves, the assertion that the parts that usually sustain the most wear are the discs and seats is accurate. The discs, which are the components that move to open or close the flow of fluid, and the seats, which are the surfaces the discs seal against when the valve is closed, are subjected to continuous mechanical stress and fluid pressure during operation. Over time, this can lead to erosion, deformation, or damage, particularly if the valve experiences high flow rates or abrasive substances.

The wear and tear on these components can affect the valve's ability to seal properly, potentially leading to leaks or failure to function. Recognizing this helps engineers and maintenance teams prioritize regular inspections and maintenance of gate valves to ensure reliable operation. Understanding the wear characteristics of these parts is crucial for the effective management of valve maintenance and performance in various systems.
