1.0 GENERAL INFORMATION
This manual shows you how to safely install, operate and use the device.
The instructions for use ALWAYS need to be available in the facility where the device is installed.
ATTENTION: installation/maintenance needs to be carried out by qualified staff (as explained in
section 1.3) by using suitable personal protective equipment (PPE).
For any information pertaining to installation/maintenance or in case of problems that cannot be solved with the instructions,
contact the manufacturer at the address and phone numbers provided on the last page.
1.1 DESCRIPTION
Device which supplies a preset and constant “downstream” pressure value (Pa) (within the intended operating limits) according
to variations in the inlet pressure (Pe) and/or the flow rate (Q). The compensated obturator ensures precision when adjusting
the outlet pressure (Pa) even with high and sudden variations in the inlet pressure.
These regulators are used in both civil and industrial installations where natural gas, LPG or other non-corrosive gases (dry
gases) are used.
Reference standards: EN 88-2 – EN 13611.
They can be equipped with the following safety devices and accessories according to the system requirements:
• downstream overpressure shut off device (OPSO): stops supply when the regulator outlet pressure exceeds
the setting value of the device. The OPSO device is always present on these devices.
• downstream minimum pressure shut off device (UPSO): stops supply when the regulator outlet pressure
drops below the setting value of the device. It also intervenes in the event of an upstream power failure. They can also be
supplied without the UPSO device.
• relief valve: discharges small gas flows outwards if overpressure occurs downstream of the regulator. This discharge
can be conveyed outwards if the installation is in a poorly ventilated environment. They can also be supplied without the
relief valve.
• outlet pressure socket.

3.0 COMMISSIONING THE DEVICE
3.1 OPERATIONS PRIOR TO INSTALLATION
•It is necessary to close the gas upstream of the device prior to installation;
•Make sure that the line pressure DOES NOT EXCEED the maximum pressure declared on the product label;
•Protective caps (if any) must be removed prior to installation;
•The pipes and inside of the device must be clear of any foreign bodies;
•IMPORTANT:
•to avoid possible pumping and/or disturbances in the gas flow, a straight pipe section equal to at least 5 DN must be
installed (downstream of the regulator);
•install manual gas closing devices (e.g. ball valves) upstream and downstream of the regulator to protect it from any
pipe leak test;
•do consider that if the regulator is equipped with a relief valve, the latter is suitable for small quantities of gas to be
discharged and CANNOT replace the relief valve installed separately as a specific device;

ES FR EN IT
14 Madas Technical Manual - 5|5.2a - REV. 0 of th Apr 2019RG/2MCS - RG/2MBZ
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;
•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 an explosive mixture arising inside the piping;
•If the regulator is installed near other devices or as part of an assembly, compatibility between the regulator and
these devices must be evaluated beforehand;
•Provide protection against impact or accidental contact if the device is accessible to unqualified personnel.
3.2 INSTALLATION (see examples 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;
•Do not use the neck of the top cover (25) as a lever to help you screw it on, but only use the specific tool;
•The arrow, shown on the body (20) 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;
•The arrow, shown on the body (20) 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” pattern
(see the example alongside);
•Tighten them, first by 30%, then by 60% and finally 100% of the maximum
torque (see the example alongside, according to EN 13611);
• 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 regulator is normally positioned before the application. Previously evaluate the possibility of installing the regulator as
shown in the installation example in 3.4;
•It can be installed in any position even if the installation shown in 3.4 (installation examples) is preferred. A pressure outlet (19)
can be found outside the regulator, downstream from it, to control the regulation pressure (Pa);
•It is necessary to connect the pulse outlet with a G 1/4 fitting downstream of the regulator (see installation examples). To
do so, remove the cap (21);
• Drain the relief valve (if any) outwards (as shown in 3.4) by removing the dust cap (24);
•It is always recommended to install a compensation joint;
•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, after installation check the tightness of the system, without subjecting the diaphragm of the regulator (therefore,
the downstream pipe section) to a pressure higher than 300 mbar (valid only for versions with standard working diaphragm).
For versions with reinforced diaphragm, check the tightness with a pressure equal to 1.5 times the regulator setting pressure.

3.3 INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
The regulator complies with Directive 2014/34/EU (formerly 94/9/EC) as group II equipment, category 2G and as group II
equipment, category 2D; consequently, it is suited for installation in zones 1 and 21 (in addition to zones 2 and 22) as classified
in Annex I of Directive 99/92/EC. The regulator is not suited for use in zones 0 and 20 as defined in the aforementioned Directive
99/92/EC. To determine the qualification and size of the danger zones, please refer to standard IEC EN 60079-10-1.
If installed and subject to maintenance in full compliance with all conditions and technical instructions provided in this manual,
the device does not pose a source of specific hazards: in particular, under conditions of normal operation, the regulator is
expected to emit a flammable substance into the atmosphere only occasionally, and specifically:
The regulator can be dangerous with respect to the presence of other devices nearby if the integrated relief valve is triggered
or if the working diaphragm (22) or the blocking diaphragm (27) fails. If the diaphragm fails, the regulator becomes a source
of explosive atmosphere emission of continuous degree and, as such, it can generate hazardous areas 0 as defined in Directive
99/92/EC.
In particularly critical installation conditions (unattended areas, poor maintenance or poor ventilation) and especially if there are
potential sources of ignition and/or hazardous equipment near the regulator in regular operation, as they may generate electric
arcs or sparks, a preliminary assessment of the compatibility between the regulator and such equipment must be carried out.
In any case, every useful precaution must be adopted so as to prevent the regulator from generating zones 0: for example,
annually verify regular operation, possibility of changing the degree of emission of the source or intervening on the explosive
substance discharge by directing it outwards. To do so, simply remove the dust caps (12) and (24) by connecting the specific
pipe (respectively, G 3/8 and G 1/8) conveyed to the outside (see installation examples in 3.4).

4.0 MANUAL RESET
•Make sure that all valves and downstream taps are closed;
•Unscrew the cap (11 );
•Lightly press the reset pin (29), wait a few moments for the pressure to balance and then fully press the reset pin (29);
•Hold down the reset pin (29), slowly open the valve downstream of the regulator;
•Release the reset pin (29);
•Then tighten the cap (11 ) back in the initial position.
5.0 FIRST STARTUP
Before commissioning, verify that:
•all of the instructions on the rating plate, including the direction of flow, are observed;
•the holes of the dust caps (12) and (24) are not clogged (regulator and shut off);
•IMPORTANT: The leak test of the piping must be performed without subjecting the diaphragm of the regulator
(therefore, the downstream pipe section) to a pressure higher than 300 mbar (for reinforced diaphragm 1.5 times
the regulator setting pressure). Use special manual gas closing devices to avoid damaging the regulator;
•The pressurisation manoeuvre of the equipment must be carried out very slowly so as to avoid possible damage.
NOTE: under no circumstances should a blind cap be installed in place of dust caps (12) and (24) as the
regulator and/or the safety shut offs may not work;
•Close the ball valve downstream of the regulator and partially open the downstream relief valve;
•Slowly open the upstream shut-off devices;
•Close the vent valve;
•Proceed by manually resetting the regulator (see 4.0);
•Close the downstream valve so as to close the regulator (the Pa value increases the SG value to fully close the obturator);
•Check the tightness of the system seals and check the internal/external tightness of the regulator, of the relief valve and of
the external sensor tube, if applicable;
•Slowly open the downstream valve and the shut-off valve;
•Check the operation of the regulator.

6.0 SETTING
Before carrying out the operations, make sure that the supplied spring/s is/are suitable for the desired Pa - OPSO - UPSO and
differential relief valve fields.
6.1 - Adjusting the maximum pressure shut off (OPSO)
•Unscrew the cap (11 );
•Use the supplied key (32) to fully tighten the adjustment ring nut of the maximum shut off (28);
•Start the system, reset the shut off device as indicated in 4.0 and make sure that there is no gas consumption (close the
applications downstream of the regulator);
Method 1:
1. Loosen and remove caps (26) and (11 );
2. Use an 8 mm socket wrench (see fig. 1a and 2a) to press on the nut (4), slowly increasing the downstream pressure
to the desired value and simultaneously keep the nut (4) pressed; use the key supplied (32) to loosen the ring nut
(28) until the device is triggered;
3. Tighten the caps back to their original position and repeat the Pa setting steps;
Method 2:
1. Alternatively, use an auxiliary gas pressure to slowly increase the downstream pressure to the desired value and
simultaneously, use the key supplied (32) to loosen the ring nut (28) until the device is triggered (so as to avoid
having to set the Pa again);
•In both cases, reset the system by following the correct procedure and verify that the trigger value is that desired by repeating
the release step 2-3 times;
•If necessary, adjust the trigger value by turning the ring nut (28) with the specific key (32).
6.2 - Adjusting the minimum pressure shut off (UPSO)
•Unscrew the cap (11 );
•Use the key supplied (32) to loosen the adjustment ring nut of the minimum shut off (30) to the minimum;
•Start the system and reset the shut off device as described in 4.0;
•Reduce the downstream pressure to the desired trigger value;
•Use the key supplied (32) to tighten the adjustment ring nut (30) until the minimum pressure shut off is triggered.
•Reset the system by following the correct procedure and verify that the trigger value is that desired by repeating the release
step 2-3 times;
•If necessary, adjust the trigger value by turning the ring nut (30) with the specific key (32);
6.3 - Adjusting the relief valve (differential DfRv)
NOTE: The relief valve (if any) in these regulators is differential, therefore the range value (DfRv) indicated must be added to
the range value of the outlet pressure (Pa).
Example: Pa=32-60 mbar - DfRv=15-40 mbar.
Means that the relief valve can be calibrated from: (Pa min + DfRv min) = 32+15=47 mbar to: (Pa max + DfRv max) =
60+40=100 mbar
Therefore the effective range of the relief valve (in this case) is 47-100 mbar.
•Start the system and set the shut off as described in point 4.0;
•Slowly close the valve downstream of the regulator;
•Loosen and remove the cap (26);
•Use the 8 mm socket spanner (see fig. 1 and 2) to fully tighten the nut (4);
•Use the 8 mm socket spanner to press the adjustment nut (4) and increase the pressure Pa, reading it on the pressure gauge,
up to the desired setting value;
•Without pressing further, slowly loosen the adjustment nut (4) until the pressure Pa begins to decrease, shown on the
pressure gauge;
•In this case, the relief valve is set to the desired value;
•Remove the socket spanner and close the cap (26).

6.4 - Adjusting the outlet pressure (Pa)
The outlet pressure Pa (unless specifically requested) is factory-set with the regulator installed as indicated in 3.4 and with
the adjustment screw (1) set approximately at the minimum setting value. The safety shut offs/relief valve are set accordingly;
If the regulator is installed in different positions, check and reset the outlet pressure Pa, and consequently the devices
incorporated in the regulator;
Adjust the outlet pressure as follows:
•Unscrew the cap (26);
•Unscrew the adjustment screw (1) and set it to the minimum setting allowed (threaded end of the top cover (25)) ;
•Start the system or make sure there is a minimum flow downstream of the regulator;
•To increase the pressure calibration downstream of the regulator, tighten the adjustment screw (1) to the desired value.
Perform the reading with a calibrated pressure gauge, installed downstream of the regulator to at least 5 DN (see examples
in 3.4);
•Screw the cap (26) back on and if necessary, seal it in that position using the appropriate seal holes (if any);
•Use pressure outlets (19)on the device only for zero flow or very low flow measurements.
7.0 - RECOMMENDED PERIODIC CHECKS
•Use a suitable calibrated tool to ensure that the bolts are tightened as indicated in 3.2;
•Check the tightness of the flanged/threaded connections on the system;
•Check the tightness and operation of the regulator/shut off/relief valve;
The final user or installer is responsible for defining the frequency of these checks based on the severity of the service conditions.
7.1 - CHECK THAT THE MAXIMUM PRESSURE SHUT OFF VALVE IS WORKING (OPSO)
Reset the shut off device and close the valve downstream of the regulator;
Method 1:
1. Loosen and remove caps (26) and (11 );
2. Use the same tool (shown in fig. 1 and 2) to press the nut (4) and slowly increase the downstream pressure until the
device is triggered;
3. Tighten the caps back to their original position and repeat the Pa setting steps (6.4);
Method 2:
1. Alternatively, use an auxiliary gas pressure to slowly increase the downstream pressure until the device is triggered
(so as to avoid having to set the Pa again).
7.2 - CHECK THAT THE MINIMUM PRESSURE SHUT OFF VALVE IS WORKING (UPSO)
•Reset the shut off device and close the ball valve upstream of the regulator;
•open the relief valve, downstream of the device, partially and slowly. As the outlet pressure decreases slowly it will cause the
minimum shut off to trigger at its setting value;
•Repeat the trigger step 2-3 times to make sure that the system functions correctly. Between one trigger and another, set the
downstream pressure back to the setting value.
7.3 - CHECK THE TIGHTNESS OF THE DEVICES (OPSO AND UPSO)
•Fully empty the downstream pipe section (wait a few seconds to allow it to empty completely). The downstream pressure
must remain at zero when the relief valve is closed.

IT EN FR ES
19
Madas Technical Manual - 5|5.2a - REV. 0 of th Apr 2019 RG/2MCS - RG/2MBZ
7.4 - CHECK THAT THE RELIEF VALVE IS WORKING PROPERLY
•Start the system and set the shut off as described in point 4.0;
•Slowly close the valve downstream of the regulator;
•Loosen and remove the cap (26);
•Use an 8 mm socket spanner to press the adjustment nut (4) to increase the pressure Pa above the preset value, while
preventing the OPSO shut off from being triggered. Use a calibrated pressure gauge for the reading;
•Remove the socket spanner. The generated overpressure will be discharged outwards and the Pa will begin to decrease to
the relief valve setting value. Relief valve operation is verified;
•Close the cap (26);
•Open the relief valve to discharge the created overpressure;
•Close the relief valve (the regulator goes to the closing pressure) and open the ball valve downstream of the regulator.
8.0 MAINTENANCE
•No maintenance operations need to be carried out inside the device. If operations must be carried out inside the
device (changing the spring, replacing the filter, etc.), it is advisable to contact the Technical Department. In any
case, before carrying out any dismantling operation on the device, make sure that there is no pressurised gas inside.
9.0 TRANSPORT, STORAGE AND DISPOSAL

In tabella sono riportati alcuni esempi per illustrare come è possibile combinare tra di loro le molle di taratura.
Per i modelli “2MCS”:
• non possono essere presenti OPSO e UPSO (quindi molle n°2 e n°3 sempre indicate con “X”);
• si può omettere lo sfioro contrassegnando con una “X” il campo molla corrispondente (n° 4);
• Codice attacchi filettati: 05=DN 32; 06=DN 40; 07=DN 50;
• Codice attacchi flangiati: 32=DN 32 FL; 40=DN 40 FL; 50=DN 50 FL
Non tutte le combinazioni sono possibili, devono essere funzionalmente compatibili. Si consiglia di contattare il nostro ufficio commerciale
per la conferma della fattibilità.
The table shows some examples to illustrate how you can combine the setting springs.
For “2MCS” models:
• OPSO and UPSO cannot be present (therefore springs no. 2 and no. 3 always indicated with “X”);
• the relief valve can be omitted by marking the corresponding spring field (no. 4) with an “X”;
• threaded connections code: 05=DN 32; 06=DN 40; 07=DN 50;
• flanged connections code: 32=DN 32 FL; 40=DN 40 FL; 50=DN 50 FL
Not all combinations are possible, they must be functionally compatible. It is advisable to contact our sales department for confirmation of
feasibility.
Le tableau reporte quelques exemples pour illustrer les possibilités de combinaison des ressorts d’étalonnage entre eux.
Pour les modèles «2MCS»:
• OPSO et UPSO ne peuvent pas être présents (donc ressorts n° 2 et n° 3 toujours indiqués avec «X»);
• il est possible d’exclure l’évacuation en marquant avec un «X» le champ ressort correspondant (n° 4);
• Code raccords filetés: 05=DN 32; 06=DN 40; 07=DN 50;
• Code raccords à brides: 32=DN 32 FL; 40=DN 40 FL; 50=DN 50 FL
Pas toutes les combinaisons sont possibles, elles doivent être fonctionnellement compatibles. Il est conseillé de contacter notre bureau
commercial pour la confirmation de la faisabilité.
