Which risk increases when rapid cycling of a hydraulic solenoid valve exceeds its rated frequency?

💡 Explanation

When the solenoid valve cycles too fast, excessive current fluctuations create heat within the solenoid coil due to resistive losses, potentially exceeding its thermal capacity and leading to insulation breakdown. Therefore, coil burnout is the main risk, rather than fluid hammer, leakage, or fluid degradation which involve alternative failure modes.
