Lifetime of drip-free performance
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 aluminum.
- Mold under extreme pressure into the three-dimensional shape of each disc.
- Fire in a 2750º F/1510° C kiln for nearly two days.
- 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 without failure.
- Install in customer’s home and enjoy no drips, no leaks, callbacks.
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 as ingenious.
