A faucet is composed of a main body, valve core, handle, filter nozzle, outlet, installation components, etc. Some faucets also have check valves, aerators, fixing bolts, fixing copper plates, gaskets, bent feet, hoses, go gauges, no go gauges, etc. Different faucets may have some differences.

The core part of the faucet is the ceramic disc cartridge. The valve core is the heart of the faucet, controlling the water flow switch, the flow rate, and the mixing ratio of cold and hot water. The quality of the valve core determines the functional reliability and service life of the faucet.

The valve cores of faucets are divided into several types based on their raw materials, including rubber valve cores, roller type valve cores, ceramic valve cores, and stainless steel ball valve cores. According to their usage functions, they are divided into three types: manual valve cores, constant temperature valve cores, and magnetic induction valve cores.

Rubber core faucets are mostly spiral open cast iron faucets, which have now been thoroughly screened; Ceramic valve core is a new generation of valve core material, with good sealing performance, stable physical performance, long service life, and a requirement of opening and closing more than 300000 times per day. Calculated based on 30 opening and closing times per day, it can be used for more than 20 years without dripping. Currently, ceramic valve core faucets are basically sold on the market.
