Filling Valves and Refilling Units
The VF06 filling valve permits simple and safe filling or refilling of closed heating systems. A pressure
reducing valve, a check valve and a shut-off facility are combined into one unit. The pressure gauge
connection enables fitting of a pressure gauge (accessory) to provide accurate checking of system
pressure after filling.
For closed heating systems to DIN 4751:
• Onto a heating circuit distributor manifold,
• in combination with a water supply distributor manifold,
• on a heating boiler via a fill hose, in the supply to or directly onto a heating boiler,
• as a filling set for trouble-free and safe initial filling of a system.
