1: refined copper body: the main leader selects the high quality refined copper ingots, adopts the international advanced gravity casting process, the precision machinery manufacturing, like nature itself -- highest quality, durable valve using sophisticated imported Taocifaxin, with diamond-like hardness. 2: ceramic valve of high quality, comfortable feel brisk, subjected to switch still more than 500000 times the smooth operation and labor saving, durability is not Water Leakage. No maintenance, no wear, aging. Suitable for hard water, from gravel or sand effect. Plating: plating process using 3: treatment of advanced, acid copper, nickel, chromium through multiple coating, plating layer with good adhesion, fine, uniform color, excellent corrosion resistance, to ensure that the product surface gloss bright, even the new constant. Lead standard: meet the national standards for lead, no damage to human health, protect you and the family without the use of harmful metals products
