Device consisting of a coupled filter regulator or pressure regulator for gas and an overpressure shut off valve (OPSO). Therefore, in addition to the stabilisation function, this device blocks the gas flow upstream, setting the entire system in safe conditions when the regulation pressure exceeds the shut off calibration pressure due to an accidental cause. Closure takes place automatically thanks to an obturator that is fully independent from the regulator.

The shut off valve can only be opened manually and only after the problem that caused the closure is found and eliminated.
