Purchase CALEFFI Autofill Valves with backflow preventer & pressure gauge. Shop automatic filling systems for hydronic heating!
FEATURES
- Automatic fast-filling: Fast fills a hydronic system to set pressure then automatically shuts off the water feed. No levers to flip or buttons to push.
- Maintains stable system pressure: Automatically maintains system pressure setting with makeup water when the hydronic system pressure decreases due to air removal through automatic air vents or blowdowns of strainers or dirt separators.
- 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 to stop makeup water if desired. Integral check valve prevents loss of system pressure if the supply water pressure drops below system pressure.
- Pre-calibration: Before charging the system, turn dial to desired system pressure with a screwdriver
- (factory preset to 15 psi). Optional downstream pressure gauge allows for easy confirmation of set pressure.
