Which outcome occurs when the proportional solenoid valve coil in a hydraulic actuator system sustains a short circuit?

💡 Explanation

When a solenoid valve coil short circuits, current bypasses the coil windings because of the low resistance path, causing immediate loss of magnetic force, and stopping control of the valve spool because it instantly springs to an open or closed position commanded. Therefore the actuator stops instantaneously, rather than drifting, oscillating, or rapidly changing temperature, which require different fault conditions.
