Emerson EZR Installation Guide

Installation Guide English – May 2002

Type EZR

Introduction

This installation guide provides instructions for installation, startup, and adjustment. To receive a copy of the instruction manual, contact your local Fisher Sales Office or Sales Representative or view a copy at www.FISHERregulators.com. For further information refer to:

Type EZR Instruction Manual, form 5468, D102600X012.

The Type EZR pilot-operated, pressure reducing regulators are used for natural gas, air, or other non-corrosive gas applications and include a Type 112 restrictor and a 161EB Series or 161AY Series pilot. For applications that have high pressure drops, using a Type 161AYM, 161EBM, or 161EBHM monitor pilot will increase the accuracy of the regulator.

P.E.D. Categories

This product may be used as a safety accessory with pressure equipment in the following Pressure Equipment Directive 97/23/EC categories. It may also be used outside of the Pressure Equipment Directive using sound engineering practice (SEP) per table below.

Pilot Type Descriptions

Type 161AY—Low-pressure pilot with an outlet pressure

range from 15 mbar to 0,48 bar (6-inches w.c. to 7 psig). Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161AYM—The monitor version of the Type 161AY pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

Type 161EB—High accuracy pilot with an outlet pressure range from 0,34 to 24,2 bar (5 to 350 psig). Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161EBM—The monitor version of the Type 161EB pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

Type 161EBH—The high-pressure version of the Type 161EB pilot with an outlet pressure range from 17,2 to 48,3 bar (250 to 700 psig).

Type 161EBHM—The high-pressure version of the Type 161EBM pilot with an outlet pressure range from 17,2 to 48,3 bar (250 to 700 psig).

Installation

Only qualified personnel should install or service a regulator. Regulators should be installed, operated, and maintained in accordance with international and applicable codes and regulations, and Fisher instructions.

If the regulator vents fluid or a leak develops in the system, it indicates that service is required. Failure to take the regulator out of service immediately may create a hazardous condition.

Personal injury, equipment damage, or leakage due to escaping fluid or bursting of pressure-containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the limits given in the Specifications section, or where conditions exceed any ratings of the adjacent piping or piping connections.

1. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded.

Type EZR

To avoid such injury or damage, provide pressurerelieving or pressure-limiting devices (as required by the appropriate code, regulation, or standard) to prevent service conditions from exceeding limits.

Additionally, physical damage to the regulator could result in personal injury and property damage due to escaping fluid. To avoid such injury and damage, install the regulator in a safe location.

Clean out all pipelines before installation of the regulator and check to be sure the regulator has not been damaged or has collected foreign material during shipping. For NPT bodies, apply pipe compound to the male pipe threads. For flanged bodies, use suitable line gaskets and approved piping and bolting practices. Install the regulator in any position desired, unless otherwise specified, but be sure flow through the body is in the direction indicated by the arrow on the body.
