← TechnologyWhich outcome occurs when water content exceeds tolerance within a hydraulic valve's control spool?
A)Accelerated valve spool corrosion cracking✓
B)Improved valve lubrication properties
C)Reduced erosion from cavitation effects
D)Enhanced thermal efficiency of actuators
💡 Explanation
Valve spool experiencing high exceedance for water content initiates *galvanic corrosion*, because the water acts as electrolyte, therefore causing accelerated pitting/cracking, rather than mitigating cavitation; lubricants are weakened by excess water.
