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 flow 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 filter with bleeding screw 

(filtration 20 microns), an adjustable restrictor and a pilot 

set to the required outlet pressure

(filtration 20 microns), an adjustable restrictor and a pilot 

adjusted to the required outlet pressure

•  A removable slam shut orifice

•  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
