A method of automated preventive and predictive maintenance for downhole valves in a well system includes receiving, at a plurality of first times, first diagnostics data of the plurality of downhole valves, where each downhole valve is at a respective first valve position at a respective first time, and the diagnostics data represents a valve condition of each downhole valve at a respective valve position and at a respective time. The method also includes receiving, at a plurality of second times, second diagnostics data of the plurality of downhole valves, where each downhole valve has been moved from the respective first valve position at the respective first time to a respective second valve position at a respective second time. The first diagnostics data and the second diagnostics data are compared. Based on results of comparing, a valve maintenance operation is selected for each downhole valve.
