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;
•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;
•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 mains voltage matches the supply voltage indicated
on the product label;
•Cut out power prior to proceeding with wiring;
•According to the plant geometry, check the risk of explosive mixture arising inside the piping;
•If the solenoid valve is installed near other devices or as part of an assembly, compatibility between the solenoid
valve and this other device must be evaluated beforehand;
•Avoid installing the solenoid valve near surfaces that could be damaged by the coil temperature;
•Provide a protection against impacts or accidental contacts if the solenoid valve is accessible to unqualified

EN
3.2  INSTALLATION (see examples in 3.4)
Threaded devices:
•Assemble the device by screwing it, with the correct seals, onto the plant with pipes and/or fittings whose threads are
consistent with the connection being attached.
•Do not use the coil (4) as a lever to help you screw it on, only use the specific tool;
•The arrow, shown on the body (7) of the device, needs to be pointing towards the application;
Flanged devices:
•Assemble the device by flanging it, with the correct 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;
•The arrow, shown on the body (7) of the device, needs to be pointing towards the application;
•Insert the relative washers inside the bolts in order to prevent damage to the flanges during tightening;
•When tightening, be careful not to “pinch” or damage the gasket;
•Tighten the nuts or bolts gradually, in a “cross” order (see the example below);
•Tighten them, first by 30%, then by 60%, and finally 100% of the maximum torque (see the table below according to
EN 13611);
Diameter DN 65 DN 80 DN 100 DN 125 DN 150
Max. torque (N.m) 50 50 80 160 160
•Tighten each nut and bolt again clockwise at least once, until the maximum torque has been achieved uniformly;
Common procedures (threaded and flanged devices):
•The device can also be installed vertically without prejudicing correct operation. It cannot be put in
upside down (with the coil (4) pointing downwards);
•During installation, avoid debris or metal residues from getting into the device;
•To guarantee mechanical tension-free assembly, we recommend using compensating joints, which
also adjust to the pipe’s thermal expansion;
•If the device is to be installed in a ramp, it is the installer’s responsibility to provide suitable supports or correctly sized
supports, to properly hold and secure the assembly. Never, for any reason whatsoever, leave the weight of the ramp only on
the connections (threaded or flanged) of the individual devices;
•In any case, following installation, check the tightness of the plant;
•Wiring cannot have cables connected directly to the coil. ALWAYS and ONLY use the connector/electronic board
recommended by the manufacturer;
•Wire the terminal board (31) with a cable 3x1 mm²,
outside Ø between 8.3 and 9.5 mm using the relative
terminals for cables, as shown in the general figure on
the side. The cable to use must have double sheathing,
be suitable for use outdoors, with minimum voltage of
500V, and minimum temperature of 105°C;

4.0  FIRST STARTUP
•Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are
observed;
•After gradually pressurising the plant, check tightness and operation of the solenoid valve by supplying/cutting
off the electricity.
4.1 - RECOMMENDED PERIODIC CHECKS
•Use a suitable calibration tool to ensure the bolts are tightened as indicated in 3.2;
•Check tightness of the flanged/threaded connections on the system;
•Check tightness and operation of the solenoid valve;
It is the responsibility of the final user or installer to define the frequency of these checks based on the severity of the service conditions.
5.0  MAINTENANCE
If the coil and/or electronic board/connector need to be replaced:
•Before performing any operation, make sure that the device is not electrically powered;
•Since the coil is also suitable to be permanently powered, high coil temperature in case of continuous operation is
entirely normal. It is advisable to avoid touching the coil with bare hands after a continuous power supply lasting
longer than 20 minutes. In case of maintenance, wait for the coil to cool down or, if necessary, use suitable protection;
NOTE: The coil and/or electronic board/connector replacement operations need to be carried out taking care to ensure the
product’s IP65 rating.

•Reassemble the cover (6) and secure it in its original position, being very careful not to “pinch” or damage the O-ring (16)
during tightening;
•Tighten the screws gradually, following a “cross” pattern, until the torque (tolerance -15%) indicated in table 4 on page 19 is
reached. Use a calibrated torque wrench to do this;
•Check the body/cover seal;
NOTE: for internal inspections, it is recommended to:
•also check the obturator’s (10) integrity and, if necessary, replace the rubber seal (12);
•replace the seals before reassembling.
6.0 - CPI SWITCH
The microswitch that signals the closed position (CPI SWITCH) is a magnetic proximity sensor with a normally open contact. It
provides a signal when the valve obturator closes.
If the solenoid valve comes with CPI, the position of the sensor is already calibrated and set, therefore, for operation you simply
need to connect it to the power supply.
If it comes separately and is installed at a later time on a solenoid valve with CPI set-up, follow the instructions provided in
paragraph 6.2
6.1 - CPI SWITCH TECHNICAL DATA
• Ambient temperature : -20 ÷ +60 °C
• Switchable voltage : max 1000 V (dc or ac peak)
• Switchable current : max 1 A (dc or ac peak)
• Switchable power : max 40W ohmic
• Resistance : 200 mΩ
• Protection rating : IP65
• Cable length : max 5m
6.2 - CPI SWITCH INSTALLATION and CALIBRATION
It is necessary to close the gas prior to installation.
NOTE: CPI connector (23) wiring must be do ensuring a product rating of IP65;
• Remove the cap (11 ) under the valve body (7) and remove the aluminium washer (found between the cap and body);
• Instead of the cap (11 ), tighten the CPI ring nut kit (21). Make sure that between body (7) and kit (21) there is the new
aluminium washer or an O-Ring (25);
• Tighten the CPI ring nut kit (21) to the valve’s body (7) with a special commercial spanner;
• Before wiring the CPI connector (23), unscrew and remove the central screw (36);
• Connect the CPI connector (23) terminals 1 and 2 in series to the signalling device. Use proper cable terminals (see the
figures in 3.2);
• Wire the CPI connector (23) with 2x1mm² cable with external Ø of 6.7 mm. The cable must be in double sheath, suitable
for outdoor use, with a minimum voltage of 500V and a temperature of at least 90°C;
• Secure the CPI connector (23), tightening (recommended tightening torque 0.4 N.m ± 10%) the centre screw (36);
• To calibrate the microswitch, loosen the fastening nut (22) and position (by screwing on or off) the adjustment ring nut (24)
so that, with the solenoid valve in a closed position, the CPI provides the signal;
• Secure the adjustment ring nut (24) in that position by tightening the nut (22);
• The kit is now installed. Open and close the solenoid valve (by supplying and cutting off power) 2-3 times to make sure the
