← TechnologyWhich outcome occurs when a hydraulic relief valve is improperly sized for a system's flow rate?
A)System pressure oscillations and instability✓
B)Actuator overspeed due to reduced damping
C)Pump cavitation from increased backpressure
D)Premature component wear from fluid starvation
💡 Explanation
When a relief valve is undersized, the valve rapidly opens and closes as it attempts to regulate pressure. Resulting in pressure cycling and unstable hydraulic system operation because of flow turbulence and valve inertia. Pressure oscillations occur, rather than overspeed, cavitation, or starvation which involve completely different failure modes and hydraulic imbalances.
