Which failure mode is induced when a hydraulic actuator's control valve pilot pressure is momentarily interrupted?

💡 Explanation

When pilot pressure is interrupted, the control valve may rapidly shift, causing sudden pressure drops leading to cavitation that forms and collapses vapor bubbles inside hydraulic actuator, damaging the surfaces. Therefore actuator rod pitting results, rather than spool seizure, pump damage or accumulator rupture that depend on different fault conditions.
