Another name for such mixers is one-handed. Cold and hot water mixed by cartridge. The cartridge is controlled by one handle, which rotates in two planes. Such mixers are sometimes erroneously referred to as ball mixers. This is because the handle rotates relative to the body, similar to the rotation of a ball. In fact, the cartridge, according to the principle of operation, is more similar to a ceramic faucet box. Adjustment of water pressure and temperature is carried out due to the movement of ceramic plates with holes. Kitchen cartridge faucets can be with a swivel body and with a molded body. Recently visited the site /gayki.html and buy good nuts.
Swivel taps can partially rotate on the sink after being fixed. Quite practical and conveniently located handle. They are quite economical, since they initially stand in the middle position (warm water), and in order to get the desired temperature, it is enough to turn the lever in the right direction, which takes much less time than the faucet box. Cartridge faucets are cheaper. Their cost does not differ from the box crane, but their service life is doubled. The only negative is the breakage of the case. If the curly gasket is broken, then you need to change the entire mixer, since it is very difficult to find it.
