Ball valves do not tolerate frequent opening and closing. The wipers wear out and manufacturers don't put much effort into the stem seals because the wipers wear out regardless.
Be mindful of materials used in your solenoid valve. Buna-N diaphragms have a similar life expectancy to your lift pump. If you can get metal, FKM, or PTFE diagrams your valve will be lifetime.
I do suggest using a normally open valve. What are the chances that you have a runaway and loss of 24V power at the same time?
