INTRODUCTION

The EZR is a pilot-operated regulator used in transmission and distribution networks or pipe lines supplying industries and commercial businesses.

The EZR can be equipped with a slam shut type OS2 (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 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

Type EZR

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 filter with bleeding screw (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 NTAOS2:

- a mechanism box (BM)

- a safety manometric box (BMS) to be connected outlet side of the regulator

The EZR is in conformity with the

PED 97/23/EC and is classified in category IV.
