R83

● Underwriters Laboratories, Inc. listed (file number

SA1089) for use with air, argon, carbon dioxide,
helium, krypton, neon, nitrogen, xenon. For use with
other gases, including oxygen, consult Norgren.

● Non-relieving and relieving models. Relieving models

allow reduction of outlet pressure even when the
system is dead-ended

● Two high pressure inlet ports and two regulated

pressure outlet ports

● Diametrically opposite inlet ports provide easy

manifolding of several regulators

● Easily replaceable valve cartridge contains valve,

valve seat, valve spring, and filter element

Technical Data

Fluid: Air, argon, carbon dioxide, helium, krypton, neon, nitrogen, and xenon.For

use with other gases, including oxygen, consult Norgren.Do not use the R83
regulator in beverage dispensing applications.Other Norgren regulators (R81
for soft drink, R82 for beer, R84 for carbonators) are available for use in

dispensing systems.
Maximum pressure: 3000 psig (207 bar)
Operating temperature: -30° to 140°F (-34° to 60°C) *

* Fluid must be dry enough to avoid ice formation at temperatures below 35°F (2°C).

Typical flow at 1000 psig (69 bar) inlet pressure, 60 psig (4 bar) set pressure and a

droop of 5 psig (0.35 bar) from set: 11 scfm (5.2 dm3/s)

Materials

Body: Brass
Bonnet: Zinc
Cartridge valve:Teflon, brass, stainless steel
Diaphragm: Acetal and nitrile
Seals: Nitrile

PORT SIZE: 1/4"
SPRING RANGE: 5 to 125 psig (0.3 to 8.5 bar)

Warning

These products are intended for use with industrial
compressed air, argon, carbon dioxide, helium, krypton, neon,
nitrogen, and xenon.Do not use these products where
pressures and temperatures can exceed those listed under

‘Technical Data’.

Before using these products with fluids other than those
specified, for non-industrial applications, life-support systems, or
other applications not within published specifications, consult
Norgren.

Through misuse, age, or malfunction, components used in
fluid power systems can fail in various modes.The system
designer is warned to consider the failure modes of all
component parts used in fluid power systems and to provide
adequate safeguards to prevent personal injury or damage to
equipment in the event of such failure.

System designers must provide a warning to end
users in the system instructional manual if protection
against a failure mode cannot be adequately provided.

System designers and end users are cautioned to review
specific warnings found in instruction sheets packed and
shipped with these products.
