What is the difference between a brass ceramic valve core and a brass valve core? Hello! I'm glad to answer your question. The brass valve core is durable, while the ceramic valve core is easily damaged. The aging resistance and wear resistance also make the service life of ceramic valve cores far exceed that of other valve cores. So ceramic valve cores have a higher cost-effectiveness than copper valve cores. In most aspects, ceramic valve cores are good. The steel ball valve core has good resistance to pressure, but the disadvantage is that the rubber sealing ring that serves as a seal is prone to wear and aging. Compared with steel ball valve cores, ceramic valve cores are more heat-resistant and wear-resistant. At the same time, ceramic valve cores themselves have good sealing performance, which can achieve high resistance to opening times and will not cause water nozzle leakage due to valve core wear. The faucet with a ceramic valve core provides a more comfortable and smooth feel, and can be quickly opened and closed. Due to the valve core being located inside the faucet, consumers cannot see the valve core when choosing, but they can simply judge the quality of the valve core based on the feel of the handle when turning it. Generally speaking, when consumers rotate the handle up, down, left, or right, if they feel light and without any obstruction, it indicates that the valve core is good.
