Which risk increases when a hydraulic actuator's bleed valve is closed too rapidly in a heavy machinery arm?

💡 Explanation

When a hydraulic actuator's bleed valve shuts rapidly, pressure surges occur because the fluid's momentum is suddenly stopped, creating a pressure wave that can exceed system component limits. Therefore, blown seals from pressure spikes result, rather than instability, thermal runaway, or cavitation, which depend on other trigger mechanisms.
