← TechnologyWhich outcome arises when a proportional control valve's input signal oscillates rapidly in a hydraulic actuator system?
A)Actuator dithering and reduced lifespan✓
B)Increased system static pressure buildup
C)Decreased actuator responsiveness to load
D)Compensated system for load variations
💡 Explanation
When the proportional valve input oscillates rapidly, the spool valve position continuously changes, causing actuator dithering from the hydraulic fluid pressure fluctuations, accelerating wear and tear. Therefore actuator dithering and shortened lifespan result, rather than increasing pressure compensation which requires slower variations.
