I would not say never, but trying to pull a valve almost a half inch using an electromagnet is a real challenge. Doing it at the speeds necessary is beyond available materials.

I designed an electromagnet once to pull 1600 lbs over a quarter inch air gap. It needed over 200 volts at 50 amps to drive it.
