Ceramic disc for the taps, which is made by adopting the international advanced manufacturing technology of dry press molding, is one of our company's leading products.
With this technology, our ceramic disc has the merits of little flatness error, good parallelism and low roughness. Besides, the ceramic disc has the features of high hardness, good air-tightness, high anti-compression strength, and high anti-bending strength.
As an ideal plumbing accessory, the ceramic disc can be applied to the single and double stage water nozzle, temperature-regulating valve, multi-functional showerhead, diverter valve, conversion valve in massage bathtub, liquefied petroleum gas control valve, and energy-saving water

Good hermetical,compressive resistance,flexual resistance,using longevity will be above 500 thousand times.
