Which 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.
