Which valve components require regular inspection as crucial parts?

Regular inspection of the disc and seat in a valve is essential because these components directly control the flow of refrigerant or fluid within a system. The disc is responsible for opening and closing the flow, while the seat provides a tight seal when the valve is closed. Over time, wear and tear can occur due to the constant opening and closing mechanism, as well as exposure to varying temperatures and pressures. Ensuring that the disc and seat are in good condition helps prevent leaks and maintain efficient system operation.

Additionally, if the disc or seat becomes damaged or worn, it could lead to loss of efficiency or even system failure, which underscores the importance of regular inspections. By examining these components, technicians can identify potential issues early and make necessary repairs or replacements to avoid more significant problems later.
