How to choose the faucet valve?

Whether the faucet is durable or not is also closely related to the valve plug. The valve core is like the heart of the faucet, and the quality is related to the life of the faucet. So how to buy a faucet valve? Let's learn more about Xiaobian.

There are three kinds of common valve cores: stainless steel ball valve, ceramic valve plug and shaft roller valve plug. The common characteristic of these three kinds of valve cores is that they have integrity, and the entire spindle is one, which makes it easy to install, repair, and replace.

The advantages of the faucet shaft roller valve are that the handle rotates smoothly, the operation is easy and convenient, the handle feels comfortable and relaxed, and the anti-aging and anti-abrasion are achieved. However, the shaft-roller spool, as an old-fashioned spool, has gradually failed to meet the demand of the crowd for the spool, and will be gradually eliminated by the market. Roller spools are now rare in the big brands.

Faucet ceramic valve core: comparable to diamonds, dripping water, ceramic material deformation is very small, compared with the metal has a higher bonding strength. Under normal circumstances, the crystalline ionic radius of the ceramic material is small, and the ion price is high and the coordination number is large. These properties determine that the ceramic material has very high tensile strength, compressive strength, elastic modulus, and hardness. However, the ceramic's own "brittleness" and difficult processing limits its application.

In the past decade, due to the development and progress of martensitic transformation toughening technology, composite material technology and nano-ceramic concepts, the “brittleness” of ceramics has been greatly improved, and its toughness and strength have been greatly improved. The scope of application is also constantly expanding. For example, the application in the faucet valve core has been greatly welcomed. Ceramic valve cores are widely used due to their low price, low water pollution, good abrasion resistance, and good sealing performance, as well as the improvement of “brittleness”. In general, the ceramic valve core plays a very good sealing role. Due to relatively strong foreign technology, some imported ceramic chips have relatively better sealing performance, stable physical properties, wear resistance, and long service life. Most of the mainstream mixers produced by most well-known brand sanitary ware manufacturers on the market have adopted ceramic valve cores.

Stainless steel ball valve faucet is currently a high technology content of a leading valve core, some high-end bathroom brands are using laser technology processing irregular seven-hole steel ball valve, as its latest tap valve product. The industry also believes that this kind of spool is more suitable for areas with poor water quality, because it is not affected by impurities in the water and will not shorten the service life. Moreover, the handle of the steel ball valve core has a larger angle in the area of ​​adjusting the water temperature, which can accurately control the water temperature and ensure that the hot water flows out quickly and accurately, and has the effect of saving 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 is more delicate and is suitable for applications where the water quality environment is poor. At present, there are some brand products on the market that use stainless steel ball valve cores.
