← TechnologyWhich outcome occurs in hydraulic actuators using spool valves when aggressive position modulation exceeds pressure limits?
A)Flow saturation and position overshoot✓
B)Increased fluid bulk modulus stability
C)Enhanced actuator temperature stability
D)Predictable system damping improvement
💡 Explanation
Flow saturation and overshoot occurs because valve "critical overlap" limits the available flow, causing missed position commands; therefore, actuation lags command values, rather than achieving dynamic range, unlike an open center valve, or stable temperature otherwise achievable.
