Which item is a primary maintenance activity listed for valves during daily checks?

• A. Visual inspection for leaks
• B. Pressure transients analysis
• C. Reconditioning seals
• D. Repainting the valve body

Answer: (A)

Daily checks focus on quickly confirming the valve is not leaking and shows no obvious signs of trouble. Visual inspection for leaks directly addresses this by letting you spot seepage from packing glands, seals, or the body right away, which is essential for safe operation and preventing fluid loss. The other tasks are more involved or not appropriate for daily checks: pressure transients analysis requires specialized instruments and interpretation and is a detailed diagnostic activity, not a routine daily check. Reconditioning seals involves disassembly and repair, which is maintenance done during scheduled outages or overhaul, not part of daily checks. Repainting the valve body is cosmetic and does not verify or improve functional integrity. So, visual inspection for leaks is the primary daily maintenance activity for valves.
