The automatic filling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet filter, anti-scale internal parts, 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 stable at a set value, automatically filling up with water as required.
This valve has been designed as pre-adjustable, which means that it can be adjusted at the required pressure value before the system charging phase.
After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached filling 50% faster than other valves. There are no levers to flip or valve to close.
Pre-assembled with the 573 series backflow preventer, the AutoFill� Combo features an atmospheric vent which is designed to protect drinking water systems from return flow, caused by back-siphoning or back pressure, of contaminated fluids. The 573 series has been specifically certified to standards CSA B64.3 and ASSE 1012.
