3.0 - COMMISSIONING THE DEVICE

3.1 - OPERATIONS PRIOR TO INSTALLATION

• 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;
Common procedures (threaded and flanged devices):
• The safety regulations on handling loads in force in the country of installation must be complied with. If the device to
be installed exceeds the weight allowed, suitable mechanical equipment and adequate slings must be used. Necessary
precautions must be taken during the handling phases so as not to damage/ruin the external surface of the device.
• With outdoor installation, it is advisable to install a protective roof to prevent rain from oxidising or damaging parts of the
device.
• According to the plant geometry, check the risk of explosive mixture arising inside the piping;
• If the valve is installed near other devices or as part of an assembly, compatibility between the valve and this other
device must be evaluated beforehand;
• Provide a protection against impacts or accidental contacts if the valve is accessible to unqualified personnel.
3.2 - INSTALLATION (see example in 3.4)
Threaded devices:
• Assemble the device by screwing it, with the due seals, onto the plant with pipes and/or fittings whose threads are consistent
with the connection being attached;
• The arrow, shown on the body (6) of the device, needs to be pointing towards the application;
Flanged devices:
• Assemble the device by flanging it, with the due seals, onto the plant with pipes whose flanges are consistent with the
connection being attached. The gaskets must be free from defects and must be centred between the flanges;
• If, after installing the gaskets, there is still an excessive space in between, do not try to reduce the said gap by excessively
tightening the bolts of the device;
