The automatic filling valve is a device consisting of a pressure reducing
valve with compensating seat, visual system pressure setting indicator,
an inlet fi lter, anti-scale internal parts, a shut-off valve (round knob on
bottom) 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 at a set value,
automatically fi lling up with water as required.
The valve is pre-adjustable, meaning it can be set to the desired
pressure value before the system charging phase.
After installation, during the fi lling or topping-off phase, the water feed
will stop when the set pressure is reached. This valve fi lls 50% faster
than other valves.
