Which effect occurs when a hydraulic actuator's spool valve experiences excessive internal leakage?

💡 Explanation

When excessive internal leakage occurs within a spool valve, fluid bypasses the actuator because of reduced flow resistance, thus decreasing the volumetric efficiency, leading to reduced actuator speed when under load. Therefore reduced actuator speed occurs, rather than increased stalled foce, decreased temp, or elevated system pressure which require increased flows.
