VF06 Sealed System Filling Valve

The VF06 is a combination filling valve for sealed heating systems, incorporating a pressure reducing valve, stop valve, a non return valve and hose connections. Factory set to 1.5 bar, the VF06 can be adjusted on site to between 0.5 and 3 bar.


The VF06 ensures that the system is not inadvertently over pressurised while filling, which can cause damage to heat exchangers, expansion vessels and joints. It also enables quick and trouble free refilling of the system should pressure loss occur.
