AUTOMATIC FILLIN& UNITS
BACKFLOW PREVENTERS
FunBSion
The AutoFill™ Combo is a pre-assembled unit consisting of an AutoFill™
and backfl ow preventer.
The AutoFill™ automatic fi lling valve is a pressure reducing valve with
a compensating seat, an inlet fi lter, a shut-off valve and a check valve.
It is installed on the water inlet piping in sealed heating systems, and its
main function is to maintain the pressure of the system to a preset value,
automatically fi lling up with water as required. This valve has been designed
as pre-adjustable, which means it can be adjusted at the required pressure
value before charging the system. After installation, during the fi lling or
topping-off phase, the water feed will stop automatically when the set
pressure is reached fi lling 50% faster than other valves. There are no levers
to fl ip or valve to close. Pre-assembled with the backfl ow preventer, it
features an atmospheric vent which is designed to protect drinking water
systems from return fl ow, caused by back-siphoning or back pressure,
of contaminated fl uids. The 573 series has been specifi cally certifi ed to
standards CSA B64.3 and ASSE 1012.
