1.0 - GENERAL INFORMATION
This manual shows you how to safely install, operate and use the device.
The instructions for use ALWAYS need to be available in the facility where the device is installed.
ATTENTION: installation/maintenance needs to be carried out by qualified staff (as explained in

1.1 - DESCRIPTION
Device consisting of a coupled filter regulator or pressure regulator for gas and an underpressure shut off valve (UPSO).
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 drops below the shut off calibration pressure value 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.
Reference standards:
• EN 88-1 (for inlet pressure up to 500 mbar)
• EN 88-2 (for inlet pressure > 500 mbar)
• EN 14382 (shut off device)
• EN 13611
