Which outcome occurs when a pilot-operated relief valve in a hydraulic system experiences excessive oil contamination?

💡 Explanation

When oil contamination is excessive, particle buildup causes spool valve sticking because contaminants interfere with the close fit between the spool and valve body, hindering movement. Therefore spool valve sticking results, rather than pressure increase, or leakage/overheating which require different causes such as spring failures , damage or aeration.
