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.
