Type EZR
INLET PRESSURE (Pu)
MOTORIZATION PRESSURE (Pm)
OUTLET PRESSURE (Pd)
ATMOSPHERIC PRESSURE (Pb)
OPTIONAL
WARNING
!
• 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).

WARNING
!
• 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.
