RG/2MCSH  -  RG/2MBHZ

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;

• To perform tightening operations, one or two calibrated torque wrenches or other controlled locking tools are required; 

• In the event of outdoor installation, it is advisable to install a protective roof to prevent rain from oxidising or damaging parts 

of the device.

• According to the system’s geometry, assess the risk of an explosive mixture forming 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 assessed beforehand;

• Provide protection against impact or accidental contact if the device is accessible to unqualified personnel.

  3.2 - INSTALLATION 

(see example in 3.4)

Threaded devices: 

• Assemble the device by screwing it, with the appropriate seals, onto the system with pipes and/or fittings whose threads are 

consistent with the connection to be assembled; 

• Do not use the neck of the top cover (

20

) as a lever for screwing, but only use the specific tool; 

• The arrow, shown on the body (

6

) of the device, must be pointing towards the application;

Flanged devices: 

• Assemble the device by flanging it, with the appropriate seals, onto the system 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 too much space, do not try to reduce said gap by excessively tightening the bolts 

of the device; 

• The arrow on the body (

6

) of the device, must be pointing towards the application;

• Insert the appropriate washers inside the bolts in order to prevent damage to the flanges while 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 on the side);

• Tighten them, first by 30%, then by 60% and finally 100% of the maximum torque (see the table here according to EN 13611);

• Tighten each nut or bolt again clockwise at least once, until the maximum torque has been achieved evenly;

• IMPORTANT

: for 2MBHZ versions (equipped with safety shut-offs) DN 65-80-100, the shut-off downstream of the regulator 

must also be connected by means of suitable fittings and pipes using the connection (

30

) (see installation example 2);

Common procedures (threaded and flanged devices): 

• The regulator is normally positioned before the application andit can be installed in any position although the installation shown 

in 3.4 (installation example) is preferred. A pressure test nipple (

23

) is fitted outside the regulator, downstream from it, to check 

the regulation pressure (Pa);

• Drain the relief valve (if any) outwards (as shown in 3.4) by removing the dust cap (

13

);

• It is always recommended to install an expansion joint;

• During installation, prevent debris or metal residues from getting into the device;

• To ensure assembly is free from mechanical tension, we recommend using expansion joints, which also make up for the 

pipe’s thermal expansion;

• If the device is to be installed in a manifold, it is the installer’s responsibility to provide for suitable and correctly sized 

supports, to properly hold and secure the assembly. Never, for any reason whatsoever, allow the weight of the manifold to 

bear only on the connections (threaded or flanged) of the individual devices;

• In any case, following installation, check the tightness of the system. To seal the downstream section of the pipe:

• feed the regulator with the inlet pressure;

• slowly close the ball valve downstream of the regulator:

• while ensuring that the relief valve and any safety shut-offs are not triggered, check that the pressure (indicated on the 

pressure gauge) remains stable (does not drop).
