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.

• Which risk increases significantly when excessive concrete creep occurs around pre-stressed steel tendons?
• Which outcome occurs when antenna **aperture blockage** distorts the signal?
• Which outcome occurs when asymmetrical saturation affects differential transformer protection?
• Which risk significantly increases due to incomplete die closure within a hydraulic forging press?
• Which limit results when a gas turbine experiences flameout?
• Which risk increases when unburnt fuel/air mixture bypasses piston rings into the crankcase?
