Regulator for Soft Drink Carbonator

Technical Data

Fluid: Carbon dioxide.The R84 regulator is designed to be used exclusively as a

carbonator regulator in soft drink dispensing systems to control cylinder gas
(carbon dioxide) pressure to the carbonator tank. Other Norgren regulators
(R81 for soft drink syrup containers, R82 for beer, R83 for industrial cylinder

gases) are available for use in other systems.
Maximum pressure: 3000 psig (207 bar)
Operating temperature: 0° to 140°F (-18° to 60°C)
Integral relief valve cracking pressure:

150 ± 5 psig (10.4 ± 0.33 bar)
Materials:

Body: Brass
Bonnet: Zinc
Valve cartridge: Teflon, brass, stainless steel
Diaphragm: Acetal and nitrile
Relief valve:Brass, polycarbonate, nitrile, aluminum
Seals: Nitrile

NOTE

The integral relief valve on the R84 regulator does not meet the
requirements of Paragraph 4.5c of NSDA Pamphlet TD02, Installation

and Operational Procedures for Pressurized Soft Drink Dispensing
Systems, dated July,1980.The end cap on the relief valve is color coded

red for visual identification and is for use only on the Norgren R84
regulator.

WARNING

For safety in systems using Norgren Model R84 regulators, the
following procedures must be followed.

1. Pressure relief valves of sufficient capacity must always be
used in the secondary (outlet) lines downstream of each
pressure regulator, whether as an integral part of the
regulator, as is the case with Norgren Model R84 Regulator,
or separately installed elsewhere in the outlet lines.Do not
remove or attempt to adjust, plug, block or otherwise defeat
the purpose of the relief valve.Do not replace a relief valve
with any but an identical model.The relief valve used on the
R84 regulator is preset and marked 150 PSIG RELIEF
VALVE. Replace only with the same 150 psig relief valve,
part number 5779-54. The end cap on the 5779-54 relief
valve is color coded red for visual identification. Failure to
provide a pressure relief valve of sufficient capacity to hold
outlet pressure below the lowest working pressure rating of
any piece of equipment installed in the outlet lines can result
in equipment damage and/or personal injury.

2. A back flow check valve must always be installed at the
regulator or at each manifold outlet in liquid dispensing
applications to prevent reverse flow through the regulator
and possible introduction of liquids and other contaminants
into the regulator.

3. Regulators must not be used where temperature or pressure
may exceed those specified in the Technical Data
paragraph.

4. The accuracy of the indication of pressure gauges can
change, both during shipment (despite care in packaging)
and during the service life. If a pressure gauge is to be used
in conjunction with these products and if inaccurate
indications may be hazardous to personnel or property, the
gauge should be calibrated before initial installation and at
regular intervals during use. For gauge standards refer to
ANSI B40.1.

5. These regulators are not intended for use in life support
systems, beer dispensing systems, with soft drink product
(syrup) containers, or industrial cylinder gas systems.
