A ceramic cartridge is an internal component of a faucet that is responsible for mixing hot and cold water and regulating its flow rate. It consists of two precision-machined ceramic discs that slide against each other. By moving the faucet lever, one disc slides over the other, thereby opening or closing the openings for water flow. Thanks to the hardness and smoothness of the ceramic material, there is minimal wear, which ensures a long service life and reliability. This mechanism also allows for smooth and precise control of the temperature and flow rate and seals well, preventing dripping. In faucets with electric heating, the cartridge performs the same function – it controls the water flow, which then passes through the heating element where it is heated.
