During engine shutdown, what happens to the fuel Shut Off Valves (SOVs)?

Explanation:
During engine shutdown, fuel shutoff valves close. This stops fuel delivery to the combustors, allowing the engine to coast down safely and reducing the risk of fuel leaks or post-shutdown fires. SOVs are normally open during operation, and the shutdown sequence signals them to move to the closed position. Some systems may include additional purge or sequencing steps, but the essential outcome is the valves closing to cut off fuel flow.
