Which outcome occurs when flow rate increases excessively through a hydraulic control valve?

A)Valve stem seizure from thermal expansion

B)Hysteresis increase from increased friction

C)Cavitation damage due to local pressure drop✓

D)Actuator stall from reduced fluid viscosity

💡 Explanation

When flow rate excessively increases through a control valve, the Bernoulli principle dictates a significant pressure drop at the valve's vena contracta causing cavitation as the fluid's vapor pressure is reached. Therefore cavitation damage occurs, rather than seizure, hysteresis or stall, which require other conditions.
