Which risk escalates when water-to-steam transition nears throttling valve?

💡 Explanation

Flow-induced vibration increases as cavitation forms pockets of vapor then collapse vigorously nearby, because the mechanism, vapor bubble collapse, couples energy into the surrounding fluid; therefore flow-induced vibration becomes a risk rather than increased valve creep under normal operation.
