Actuated valve controls are common in mining and materials processing.
they are most often pnuematic (because if those fail they let you know how and where) but are also available in electrical.
I disagree with relaibility being their drawback. Expense and bulk is. Also, in your case, they do not solve anything....You now just get to worry about whether they are working or not when you press the button, instead of diggin down to do it by hand.
It's a nice idea, it is possible, but you shouldn't, is pretty much the summary of my answer.
