Which outcome arises when thermal expansion seizes a spool valve controlling high-pressure hydraulic fluid?

💡 Explanation

When a spool valve seizes from thermal expansion, uncontrolled actuator movement results because the valve can no longer properly direct or block fluid flow, leading to uncontrolled bypassing. Therefore, actuator movement is the outcome rather than relief chatter, cavitation, or reservoir overheating, which require different initiating conditions.
