Have you looked into another valve company ?

No

I retired a few years ago from a large company and we had hundreds of
valves similar to that and very few of them failed, especially the
coils. Most did operate on 120 volts.

Of course at 120V the wire would be twice the diameter. If it is
corrosive flux at work, it would take longer to eat it away. If it is
failing Pbfree solder bonds, who knows.

Not sure how the valves are in your oven, but maybe you could try 2 of
the 120 volt coils in series.

I am considering that. Meanwhile SWMBO is considering a replacement
oven (which as you'd all know, means a complete new kitchen)
