The heart of the faucet is its valve core. To choose a good faucet, we must first understand the valve core of the faucet. At present, there are three common valve cores: stainless steel valve core, copper valve core and ceramic valve core.
Stainless steel valve core is a kind of faucet valve core with high technology content at present, but stainless steel material is easy to rust and pollute water quality if it is not up to standard. Copper valve core is the heaviest and most expensive valve core, and the quality of copper is also very high, otherwise it is easy to deposit scale. Ceramic valve core is the best valve core, which has the characteristics of strong wear resistance, good sealing, long service life and high temperature resistance, and is widely used in many high-quality products. Imported ceramic valve cores like American Standard are sintered and polished at high temperature as high as 1400 degrees Celsius, which is durable.
