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 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 3).
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;
• Valve pipes and insides must be clear of any foreign bodies;
If the device is threaded:
• make sure that the pipe thread is not too long, to prevent damaging the body of the device when screwing it on;
If the device is flanged:
• make sure the inlet and outlet counter-flanges are perfectly coaxial and parallel in order to prevent unnecessary
mechanical stress to the body. Also calculate the space to insert the seal gasket;
• With regard to tightening operations, equip yourself with one or two calibrated torque wrenches or other controlled locking
tools;
