INDIANAPOLIS, IN, Mar. 4, 2009 -- Delta Faucet Company recently unveiled its patented DIAMOND™ Seal Technology, an exclusive new water delivery system that eliminates contact with potential metal contaminants such as brass, copper or lead, keeping water as pure as it entered the faucet.
It also provides guaranteed protection from leaks and drips. Comprised of a next generation DIAMOND™ valve and InnoFlex™ waterways, the system reduces the number of potential leak points, simplifies installation and provides long lasting performance.
"DIAMOND Seal Technology is the future of faucets. The lead-free waterway system ensures that once the water enters the faucet it does not come in contact with metal contaminants." said Rick Roetken, vice president of marketing, Delta Faucet Company "This groundbreaking engineering uniquely harnesses the durability of diamond, to create a leak-free valve which lasts up to 10 times longer than the industry standard." (Industry standard is based on ASME 112.18.1 at 500,000 cycles.)
The DIAMOND valve is an integrated ceramic valve cartridge featuring one ceramic disc and one diamond-embedded ceramic disc. As the two discs in the DIAMOND valve move against each other, the diamond-embedded ceramic disc constantly polishes the uncoated ceramic disc, preventing buildup of calcium and mineral deposits and ensuring smooth, consistent operation over the life of the faucet.
Once inside the faucet, water is not in contact with potential metal contaminants, such as brass, copper and lead. DIAMOND Seal Technology by Delta Faucet Company also satisfies California statute AB 1953, mandating that by January 1, 2010, the weighted average lead content in pipes, fittings and fixtures used to convey drinking water cannot exceed 0.25% lead on wetted surfaces.
The threat of leaks is all but eliminated with DIAMOND valve and InnoFlex™ one-piece waterways. The DIAMOND valve is a closed system, meaning there are no dynamic seals to wear out. Water does not enter the top half of the cartridge, eliminating the possibility for leaks under the handle. InnoFlex™ waterways are made using a proprietary blend of PEX (cross-linked polyethylene) -- a highly-engineered, very durable polymer material that is resistant to heat and freeze damage.
The Delta DIAMOND valve is built to last up to 10 times longer than the industry standard. (Industry standard is based on ASME 112.18.1 at 500,000 cycles.) Testing demonstrates that the DIAMOND valve will last more than 5 million cycles. Waterways have been stress tested at 500 psi (the same psi as fire hydrants), and up to 200º F and will not pit, pinhole, scale or corrode.
All the parts needed for installation are in the box. The InnoFlex™ waterways' integrated supply lines are 38" long from the valve base to the fittings, with a minimum of 32" below the deck, so they can be connected directly to the hot and cold water shut-off valves. No intermediate riser connections are needed, eliminating two potential leak points. To adjust them to the right length, the flexible supply lines can be coiled or cut to length using ferrule inserts included with every Delta® DIAMOND Seal Technology faucet.
A two-function handle limit stop is easily accessible by removing the handle. The handle limit stop allows the user to choose between a full range of handle motion (which is pre-set at the factory) or to restrict handle motion to a 50/50 mix of hot and cold water.
DIAMOND Seal Technology is available on the Delta brand's most popular pull-out and pull-down kitchen faucets including Signature®, Saxony®, Victorian®, Leland®, Palo®, Allora®, and Pilar™. In January 2009, DIAMOND Seal Technology will begin to phase in on Delta single-handle kitchen and single-handle lavatory faucets.
