← TechnologyWhich risk is elevated when the poppet valve in a hydraulic actuator sticks closed during rapid cycling?
A)Fluid temperature increase due to throttling
B)Creep caused by increased backpressure
C)Excessive wear due to rapid deceleration
D)Structural fatigue due to impact loading✓
💡 Explanation
When the poppet valve sticks closed during rapid cycling, the actuator rod impacts the cylinder end because the damping effect of the fluid is lost, leading to impact loading. Therefore structural fatigue risk increases, rather than temperature increase, creep, or excessive wear which would require blocked pathways/low pressure control.
