2.2 - SIL LEVEL
For models in compliance with Regulation (EU) 2016/426 (see table in 9.0),
the SIL level of the stand-alone solenoid valve
is SIL 2; when two solenoids are installed in series and the relative leak test (Valve Proving System), certified according to
EN 1643, the achieved level is SIL 3, as set forth in EN 676:2008. The solenoid valve has PL d level. For further data refer
to the SIL LEVEL table (table 2).
3.0 - COMMISSIONING THE DEVICE
3.1 - OPERATIONS PRIOR TO INSTALLATION
All installation operations must be carried out in the absence of an explosive atmosphere.
• It is necessary to close the gas upstream of the valve prior to installation;
• Make sure that the line pressure
DOES NOT EXCEED
the maximum pressure declared on the product label;
• Any protective caps (if any) must be removed prior to installation;
