- Anti-scale with visual system pressure indicator
- Automatic fast-filling - Fast fills the system to set pressure then automatically shuts off the water feed, no levers to flip or valves to close
- Maintains stable pressure at pre-setting - Fill the system to a set pressure and maintain that pressure setting regardless of inlet pressure variations
- Anti-scale polymer materials - Prevents scaling on internal sliding surfaces, assuring stable pressure control and long operating life
- Built-in shut-off valve and check valve - Allows isolation of system from supply and check valve prevents loss of system pressure if the supply water drops below system pressure
- Pre-calibration - Before charging the system, use a screwdriver to turn dial to intended system pressure, downstream pressure gauge is not required
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 (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 filling 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 filling or topping-off phase, the water feed will stop when the set pressure is reached. This valve fills 50% faster than other valves. There are no levers to flip or valve to close.
