Which risk increases when a hydraulic actuator operates near vacuum?

💡 Explanation

Cavitation increases because the rapidly changing pressure causes bubbles to form and collapse violently, eroding surfaces. Therefore, internal cavitation is the greater risk, rather than pressure surges arising from changes in flow parameters.
