← TechnologyWhich risk increases when using proportional valves for rapid, precise control of hydraulic actuators with accumulators?
A)Valve spool overheating and seizure
B)Accumulator bladder degradation and leaks
C)Sudden pressure spikes; water hammer
D)Cavitation, actuator damage, resonance✓
💡 Explanation
The risk of cavitation increases with rapid cycling because the proportional valve attempting fast directional changes can cause localized vacuum conditions. Therefore, cavitation occurs rather than smooth flow because the valve closure timing exceeds the hydraulic fluid's ability to respond.
