Mine only stick if I let them slam shut. Don't let them slide/slam shut
on their own.

And keep the screw handle mid point in the travel so that you can loosen.

The same basic rule applies to gate style water shutoffs. Open them fully,
and then close them by at least a 1/8 turn. Leave yourself a little wiggle room
in case the innards get corroded and it won't turn towards close.
