Safety & Environmental Protection (Deck) USCG Question #999 (Set 31)

What is the proper direction of flow through a globe valve when the valve is installed to be in a normally open position?

Official USCG Answer & Rule Citation

Correct Answer: Option C — From below the seat

Globe valves installed with flow coming from below the seat ensure that system pressure acts upward against the disc when closed, helping maintain a tight seal. Furthermore, if the stem fails or separates from the disc, system pressure will not force the valve shut, preventing accidental flow interruption.
