Which risk increases when a proportional valve in a hydraulic servo system experiences excessive internal leakage?

💡 Explanation

When internal leakage occurs, the proportional valve loses precise control because the intended flow rate does not reach the actuator; this deadband requires higher input signals to initiate movement. Therefore, reduced actuator bandwidth results, rather than thermal stress, seal wear, or accumulator failure which involve totally distinct mechanisms and conditions.
