← TechnologyWhich outcome occurs when a hydraulic directional control valve rapidly switches under high flow?
A)Water hammer causing pipe rupture✓
B)Internal leakage reducing system pressure
C)Actuator cavitation intensifying vibration
D)Pump starvation increasing oil temperature
💡 Explanation
When a directional control valve rapidly switches, the sudden flow change induces a pressure surge that is known as water hammer, because the fluid's momentum cannot stop immediately and compresses against closed valve. Therefore pipe rupture is the ultimate outcome, rather than leakage, cavitation, or starvation, which relate to slower or continuous issues.
