Compact backflow preventers

The range of series 580 compact backflow preventers was introduced with the aim of protecting the domestic water supply line, even in contexts lacking sufficient space.‎
In distribution networks, inlet pressure drops may cause potentially polluted water to flow back into the mains, thus generating a dangerous situation for human health.‎
Backflow preventers are specially designed to prevent this backward flow and to keep the common distribution network completely separated from the domestic/commercial/industrial water systems.‎
As the upstream pressure drops, the internal check valves close, thus blocking the backward flow of water.‎ The lack of pressure on the diaphragm that controls the drain valve causes the latter to open, enabling the water contained inside the intermediate chamber to flow out; this prevents the network water from coming into contact with the potentially polluted water present in the system.‎
Series 580 type-BA backflow preventers (EN 12729-certified) have a self-contained cartridge, where all the main components are integrated, mounted obliquely: this feature makes them highly compact and installable on vertical, horizontal and oblique pipes.‎ Moreover, thanks to the various accompanying kits, they can also be installed on the point of use and in place of conventional outdoor taps.‎
This construction feature was exploited to produce an automatic charging unit.‎ This unit combines protection of the backflow preventer with the pressure control offered by the compact charging unit.‎
The 580010 automatic charging unit can be installed on both horizontal and vertical pipes.‎
