The FRG/2MB MAX filter regulator or RG/2MB MAX regulator is made up of the coupling of a filter regulator or regulator and a shut off valve of over pressure.
It works as a closing regulator but when the regulation pressure exceeds, for accidental causes, the shut set pressure, the latter automatically intervenes and shuts upstream (with a bell closure completely independent from the regulator) the gas flux for the plant safety.
The opening of the shut valve is only manual after verifying the causes that provoked the shut.
