Which outcome primarily occurs if a hydraulic directional control valve spool sticks mid-stroke during rapid cycling?

💡 Explanation

When a directional control valve spool sticks mid-stroke, a partial blockage occurs because the flow path is restricted unevenly, leading to erratic actuator movement as flow varies unexpectedly. Therefore actuator speed fluctuates, rather than pressure relief chattering, fluid overheating, or pump cavitation which stem from distinct hydraulic system faults.
