Description

Caleffi AutoFill boiler fill valve & FlowShield backflow preventer combo with 1/2" female NPT connections. Factory pre-set to 15 psi. Commonly used for cold water feed into a heating system.
AutoFill valve is packed with features, including a 1/8" NPT oulet (capped off, for optional pressure gauge), visual pressure setting indicator (adjustable from the top with a standard flat head screwdriver), positive shut-off (round knob at the bottom), built-in & removable fine mesh screen/strainer, anti-scale internal components (prevents scale build-up) and many others.
Unlike with other boiler fill valves, where it is necessary to hold the fill lever open and wait until the system fills, Caleffi AutoFill feature automatically fills the system to the pre-set pressure.
FlowShield dual check valve with atmospheric air vent protects the potable water supply from cross-contamination caused by back-siphon or back pressure.
Made in Italy.
