670 Series Panel-Mounted Loading

Regulator Assemblies

WARNING

Fisher

regulators should be installed,

operated and maintained in accordance

with federal, state and local codes, rules

and regulations and Emerson Process

Management Regulator Technologies,

Inc. instructions.

If 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.

Call a gas service person in case of trouble.

Only a qualied person must install or

service the regulator.

Introduction

The 670 Series panel-mounted loading regulator assemblies

are used primarily for manually controlling pressure to

diaphragm control valves or as remote pressure loaders for

pressure-balance gas regulators. They are also widely used

for remote control of gas pressure to burners in renery tube

stills, power plants and similar process furnaces.

Principle of Operation

The 670 Series regulators are set manually to control supply

pressure to diaphragm control valves or gas regulators.

Instrument and manual loading pressures are read from the

pressure gauges of the regulator. If pressure to the valve

needs to be adjusted, the regulator handwheel is turned

clockwise to increase the supply pressure or counterclockwise

to decrease the supply pressure.

Installation

Inspect the panel after it is removed from its packing.

Connect a 1/4 in. / 6.4 mm pipe line from the operating

supply pressure to the connection marked “IN” on the

pressure regulator.

One and two-gauge panels: Connect a line to the diaphragm

casing of the main valve or regulator and run it to the

connection marked “OUT” on the panel regulator. When

installing a two-gauge panel, connect a line from the control

pressure line to the upper diaphragm casing and to the

control pressure gauge (instrument loading pressure) in the

back of the panel (see Figure 2).

Two-gauge panel with a three-way changeover valve:

Connect the air supply, diaphragm connection and

instrument loading pressure line to the panel regulator as

shown in Figure 4.

Overpressure Protection

WARNING

Overpressuring any portion of this equipment

may cause damage to regulator parts, leaks

in the regulators or personal injury due to

bursting of pressure-containing parts or

explosion of accumulated gas.

To avoid overpressure, provide appropriate

overpressure protection to ensure that none of

the pressure limits will be exceeded.

The regulator assembly should be inspected for

damage after any overpressure condition.
