← TechnologyWhich outcome occurs when dissolved gas content in hydraulic fluid exceeds its saturation point within a control valve?
A)Cavitation erosion downstream of valve✓
B)Increased fluid bulk modulus upstream
C)Reduced actuator speed due to foaming
D)Valve stiction due to deposit formation
💡 Explanation
When dissolved gas exceeds saturation, gas bubbles form locally due to pressure drop past the restrictions, which then implode as pressure recovers, causing cavitation erosion. Therefore erosion occurs downstream, rather than increased modulus, reduced speed, or stiction which arise from distinct mechanisms relating to the hydraulic fluid.
