Within a hydraulic actuator driving a robotic arm, which consequence results when the spool valve's sharp edges erode due to fluid impingement?

💡 Explanation

Erosion of valve edges allows pressure bleed, leading to reduced control and instability. This outcome is caused by the mechanism of fluid-induced cavitation erosion, because localized pressure drops cause vapor bubbles. Therefore, positional accuracy drops, rather than improvements in thermal or sealing behaviors.
