Which risk increases when a hydraulic directional control valve experiences spool binding in a high-pressure system?

💡 Explanation

When a valve spool binds, it prevents proper sealing because it cannot fully close ports, leading to internal leakage and fluid recirculation, which raises temperature due to viscous friction. Therefore overheating is increased, rather than cavitation, actuator creep or corrosion which arise from other distinct failure modes.
