2.2 - SIL LEVEL
The SIL level of the stand-alone solenoid valve is SIL 2; when two solenoids are installed in series and the relative seal 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).

3.1 - 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;
• Valve pipes and insides must be clear of any foreign bodies;
• Make sure that the pipe thread is not too long, to prevent damaging the body of the device when screwing it on;
• In accordance with EN 161 a suitable filter must be installed upstream of a gas closing safety device;
• With outdoor installation, it is advisable to provide a protective roof to prevent rain from damaging the electrical parts of
the device.
• Prior to carrying out any electrical wiring operations, make sure that the main voltage matches the supply voltage indicated
on the product label;
