INSTALLATION
• 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 appropri-
ate operating conditions.
• Version with integral slam shut, verify that the safety
manometric box (BMS) and spring correspond to the appro-
priate operating conditions on the outlet side of the regulator.
• The equipment should not receive any type of shock, espe-
cially 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.
All interventions on the equipment should only be performed by
qualified and trained personnel.
