Which operational risk rises in hydraulic servovalves as fluid temperature increases, approaching the vapor pressure?

💡 Explanation

As temperature nears fluid vapor pressure, cavitation risk intensifies because small pressure drops readily cause vaporization in constrictions; vapor bubbles then collapse damaging valve surfaces. Therefore cavitation erosion risk rises, rather than leakage, weeping or stiction, which depend on viscosity changes or material incompatibility issues.
