Which outcome occurs when high-speed directional control valve rapidly closes in a hydraulic actuator circuit?

💡 Explanation

When the valve closes rapidly, pressure waves reflecting off the actuator inertia superpose and create negative pressure waves causing localized boiling or cavitation because the local pressure drops below the vapor pressure. Therefore pressure spikes induce cavitation rather than flow viscosity, actuator lockup or damping, each of which require other mechanisms.
