How do you make the best valve in the world? By
producing a high-tech ceramic that is almost as hard as a diamond, using
technology pioneered in American Standard’s laboratories.
Start with alumina oxide powder, which is oxidized
Mold under extreme pressure into the
three-dimensional shape of each disc.
Fire in a 2750º F/1510° C kiln for nearly two
Polish the mating surfaces of the discs with diamond
paste to achieve a near perfect flatness (approximately 1/100,000 inch). How
flat is it? Flat enough that the ceramic discs cling to each other just like
metal magnets. That’s flat.
Test to survive over one million on/off cycles
Install in customer’s home and enjoy no drips, no
What’s the big deal about flatness? Discs that cling so tightly together are not
affected by supply line debris, such as sand or solder. There is simply no room
for anything to come between those two discs.
A perfect quarter turn of the handle starts and
stops the water flow, and the handles won’t stiffen, leak, or loosen with
repeated use. The fired-hardened discs do not absorb water or soften over time.
For many years, such ingenuity was found only in
the world’s most expensive faucets. American Standard offers ceramic disc
valving on all of its faucets, at every price point. We can do that because we
make our own discs. We also do it because we believe that plumbers will be more
successful generating referrals, not servicing leaks from faucets that are not
