Which statement about post indicator valve checks is true?

• A. The rod remains attached to the valve
• B. The valve is fully open
• C. The indicator must be reset after testing
• D. The rod is detached from the valve

Answer: (A)

Post indicator valve checks ensure the linkage between the valve stem and the position indicator remains intact so the indicator correctly shows the valve’s status. The essential point is that the rod stays attached to the valve; this prevents misrepresentation of the valve position and maintains reliable indication in an emergency. The test doesn’t require the valve to be fully open—it's about verifying operation and that the indicator reflects the actual position. The indicator typically stays aligned with the valve’s position automatically, so a separate reset after testing isn’t required.
