Single-lever mixers, or joysticks, got their second name from the similarity of control to computer game consoles.
Operating principle and advantages of a single-lever mixer
The traditional two-valve mixer yielded the crown to the "joystick" with its appearance. Today, most offered mixer models are of the single-lever type. The functions of both valves have been taken over by a special ceramic cartridge that simultaneously regulates temperature and flow, mixing hot and cold water. The cartridge's special insoluble lubricant ensures smooth and free movement of the control lever throughout its service life.
The "joystick" concept provided this type of mixer with the following advantages:
* Reduced number of moving parts, increasing product reliability and durability;
* Allowed for one-piece castings of the spout and mixing chamber;
* Replaced rotary joints with sliding ones, eliminating the capricious part like a gland;
* Made mixer operation as simple and convenient as possible.
To appreciate the variety of shapes of single-lever mixers, a separate large description dedicated to the design and construction of spouts is required.
Key features of quality "joysticks"
Leading sanitary fittings manufacturers Grohe, Hansgrohe, Jacob Delafon, and others have set a certain standard for a minimum "gentleman's set" of a quality mixer, which includes:
* Base material – brass or alloy steel, no silumin or other ersatz materials;
* Quick-installation system (except for wall-mounted mixers);
* Water flow regulation (economy mode);
* Chrome-plated electroplated finish;
* Water flow aerator.
With an increase in product class, single-lever mixers gain:
* Pull-out spout;
* Thermostat;
* Water filters;
* Limescale protection system;
* Automatic spray mode switching;
* Touchless operation control.
The high precision of manufacturing parts of a single-lever mixer imposes increased requirements on tap water quality, so models without a filter risk damage from sand grains entering the cartridge, causing premature failure. For absolute reliability of "joysticks," it is advisable to equip the water supply with mechanical cleaning filters.
