Which risk increases when proportional valve deadband setting on a hydraulic actuator is excessively reduced?

💡 Explanation

When a proportional valve deadband is excessively reduced, valve spool dithering (caused by minute control variations or noise) leads to increased actuator oscillations because the system becomes more sensitive to disturbances. Therefore, instability around the setpoint, rather than other factors, will increase since other events call for alternative trigger issues to start.
