Which components of a valve require regular inspection?

The disc and seat of a valve are critical components that require regular inspection to ensure proper functionality and sealing capability. The disc is the moving element of the valve that controls the flow of fluid, while the seat is the surface against which the disc closes to prevent flow when the valve is in the closed position. Over time, these components can wear due to factors such as fluid turbulence, temperature variations, and pressure changes.

Regular inspection of the disc and seat is essential to identify any signs of wear, corrosion, or damage that could compromise the valve's sealing ability. If the disc or seat is damaged, it can lead to leaks, reduced efficiency, or complete valve failure, which can have serious implications for system performance and safety. Consequently, maintenance checks focusing on these components are vital to ensure the reliability and longevity of the valve in its application.
