Ball type float valves are deprecated technology

Maybe, but they are *far* more reliable than Torbeck type ones.

Depends on your water. if lime isn't a probem, then a Torbeck will
out-last the rubber seat of a traditional ball valve.

I always fit Torbecks to toilets because they fill faster (flow isn't
throttled gradually as the cistern fills). I don't bother to use them
for header tanks though.
