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

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.
