The AutoFill™ automatic filling valve is a pressure reducing valve with
a compensating seat, an inlet filter, 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 filling 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
filling or topping-off phase, the water feed will stop automatically when the
set pressure is reached. There are no levers to flip or valve to close. Preassembled with the backflow preventer, it features an atmospheric vent
which is designed to protect drinking water systems from return flow, caused
by back-siphoning or backpressure, of contaminated fluids. The 573 series
has been specifically certified to standards CSA B64.3 and ASSE 1012.
