Which risk dramatically increases due dynamic pressure changes in a hydraulic servovalve system with rapid actuator movements?

💡 Explanation

Cavitation erosion on valve seats happens because the rapid pressure drops cause the fluid to vaporize, forming bubbles that implode and release energy via the mechanism of vapor collapse. Therefore, significant erosion occurs, rather than thermal expansion, bulk changes, or contaminant increases that occur under steady-state conditions.
