•
The regulator is installed on horizontal pipeline.
Version with slam shut, the release relay is situated
towards the bottom (see schematic).
•
Installation according to EN12186 recommended.
•
Install according to direction of fluid flow (arrow).
•
When assembling with adjacent elements care
must be taken not to create pressure force on the
body and the assembling elements (bolts, O-rings,
flanges) should be compatible with the geometry and
working conditions of the equipment.
•
If the case arises a support must be used to avoid
pressure force on the body (a support can be installed
under the flanges).
•
Version with integral slam shut , connect the safety
manometric box (IS) to the impulse at 4D on a straight
run of the outlet pipe.
•
It is recommended to separate the slam shut impulse
line (IS) from that of the pilot (IP). Do not connect the
impulses on the lower generator line.
•
It is recommended to install an isolation valve and an
atmospheric valve, which can be useful for slam shut
tripping and verifications.
•
No modification should be made to the structure of
the equipment (drilling, grinding, soldering...).

•
It is recommended to install a servicing valve on the
outlet pipeline to facilitate adjustments and bleeding
off to the atmosphere.
• Verify that the inlet side is protected by an
appropriate device(s) to avoid exceeding the limits of
utilization (PS, TS).
• Verify that the limits of utilization correspond to the
appropriate operating conditions.
• Version with integral slam shut, verify that the safety
manometric box (BMS) and spring correspond to the
appropriate operating conditions on the outlet side
of the regulator.
• The equipment should not receive any type of shock,
especially the release relay.
• The user should verify or carry out a protection
adapted to the environment.
• Fire, seismic and lightening are not taken into
consideration in standard regulators. If required, a
special product selection and/or specific calculations
may be supplied according to specific requirements.
•
Version without integral slam shut, verify that a
pressure limiting device on the outlet side of the
regulator guarantees a pressure limit inferior or
equal to the pilot PS.
