Introducing Caleffi AutoFill™ Automatic Filling Valve for Commercial SystemsSubscribe to RSS feed



The 5350 Series AutoFill™ fast fill/pressure reducing valve maintains system pressure at a set value, automatically feeding water as required when installed on the water inlet piping in closed hydronic systems. Because the valve is pre-adjustable, the system pressure can be adjusted to the appropriate pressure before the system charging phase
and then will automatically shut off the water feed. A pre-assembled internal cartridge contains the controlling components as a self-contained unit, facilitating ease of inspection and maintenance procedures. Available in ¾” sweat or union connection, it includes an integral downstream pressure gauge and pressure setting adjustment knob.
