Roller spool: Its advantages are smooth handle rotation, easy and simple operation, comfortable and easy hand feeling, aging resistance and abrasion resistance. However, as an old-fashioned cartridge, the roller cartridge has been gradually unable to meet the needs of the current population for the spool, so it will be gradually eliminated by the market. Roller cartridges are rarely seen in the leading brands produced by major brands.

Stainless steel ball valve: It is currently a leading valve core with high technological content. Some high-end bathroom brands use irregular seven-hole steel ball valve cores processed by laser technology as the valve cores of their latest faucet products. Industry insiders also believe that this valve core is more suitable for areas with poor water quality, because it is not affected by impurities in the water and will not shorten its service life. Moreover, the handle of the steel ball valve core has a larger angle in the area where the water temperature is adjusted, which can accurately control the water temperature, ensure that the hot water flows out quickly and accurately, and save energy. However, the production cost of the stainless steel ball valve core is higher than that of other types of valve cores. At the same time, the manufacturing process requirements are more refined, which is suitable for applications in places with poor water quality.
