    The over pressure valve is activated when, due to a system fault, the system pressure exceeds the adjusted value. In these cases, it lets the fluid drain outside the primary circuit, thus preventing the pressure from increasing and damaging any component. The adjustment range is from 0.5 to 10 bar. In the MVW01, it is adjusted to 6 bar. 6.4.8 Automatic Degasser Valve The automatic degasser valve allows the release of the existing air from the primary circuit.
