Introduction
The Type EZR is a pilot-operated regulator used in
transmission and distribution networks or pipe lines
supplying industries and commercial businesses.
The Type EZR can be equipped with a slam shut Type OS2
(Type EZR body change) which permits the gas ow to be
cut off rapidly and totally in the case of under or over outlet
regulator pressure.
Description
The Type EZR consists of:
A version without integral slam shut:
• A body («E body» type), a bonnet
• A regulation subassembly consisting of a slotted cage and
a diaphragm/plug
• A travel indicator, an inlet screen
• A pilot assembly consisting of a lter with bleeding screw
(ltration 20 microns), an adjustable restrictor and a pilot
set to the required outlet pressure

A version with integral slam shut:
• A body («X body» type), a bonnet, a connecting part
• A regulation subassembly consisting of a slotted cage
and a diaphragm/plug
• A travel indicator
• A pilot assembly consisting of a lter with bleeding screw
(ltration 20 microns), an adjustable restrictor and a pilot
adjusted to the required outlet pressure
• A removable slam shut orice
• A integral O-ring tightshut valve/bypass assembly
• A release relay Type OS2 according to D103683X012_
OS2_IM:
- a mechanism box (BM)
- a safety manometric box (BMS) to be connected outlet

Operation
Regulator
The Type EZR is a pilot-driven, diaphragm/plug regulator.
Tight shutoff is achieved by the diaphragm/plug pushing
against the slotted cage, the force of the closing spring and
the inlet pressure.
• Opening
As the ow increases, the outlet pressure Pd
decreases on the outlet side of the regulator and on
the pilot diaphragm.
Due to the force of the spring, the pilot opens.
The pilot ow increases, the pressure loss through the
pilot restrictor increases.
The modulated pressure Pm decreases.
The force of the closing spring and that of the Pm
becomes inferior to that provoked by the Pu, the
regulator OPENS.
• Closing
As the ow decreases, the Pd increases outlet side of
the regulator.
The force of the pilot diaphragm is overcome by the force
of the spring, the pilot closes.
The pressure loss through the pilot restrictor decreases.
The force of the closing spring and that of the Pm
becomes superior to that provoked by the Pu, the
regulator CLOSES.
Slam Shut
The pressure of the zone to be protected (generally the pipeline
on the outlet side of the regulator and after the slam shut) is
sensed by the safety manometric box (BMS).
If the pressure exceeds the set tripping pressure, the release
relay frees the valve plug.
Due to the force of the closing spring and the uid (trying to
close), the valve plug closes on the orice.
The gas ow is obstructed until the fault has been corrected
and the mechanism box manually rearmed.
To reopen the valve plug an equal pressure balance on inlet
and outlet sides of the regulator is required.
The mechanism box is rearmed after opening the
internal bypass.
Rearming and balancing are achieved at the same time.

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uidow(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,
anges)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anges).
• 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verications.
•Nomodication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speciccalculations
maybesuppliedaccordingtospecic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qualiedandtrainedpersonnel.
