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

Pilot-Operated Regulator

Figure 1. Type EZR Pilot-Operated Regulator

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

side of the regulator

The Type EZR is in conformity with the

PED 2014/68/EU and is classied in Category IV.
