Ball valves are used to join the water supply systems – washing and washing machines. At the same time, flexible connectors with a unit nuts are used. For the connection of sanitary devices, for example, flush tanks or mixers, models with angular placements are provided, which are connected using metal or flexible connections with fittings. Using such cranes, you can disconnect a separate device from the water supply without blocking the entire water line. The design of household ball valves does not differ from the taps used in industrial installations, however, they use a more decorative design, for example, a chrome surface. The temperature conditions of the operation of household cranes are from 0 to 80 degrees, with a maximum working pressure of 16 bar.
