R81 Regulator and C81 Configurations
● Underwriters Laboratories, Inc. listed (file number
SA1089)
● The R81 regulator and C81 regulator configurations
with integral relief valve and outlet check valves meet
the requirements of paragraphs 4.5 and 4.6 of NSDA
Pamphlet TD02, Installation and Operational
Procedures for Pressurized Soft Drink Dispensing
Systems, dated July, 1980.
● Integral relief valve easily replaced without
disassembly of regulator and without affecting relief
pressure setting
● Back flow check valve, or manifold with integral
check valve at each outlet, can be installed in
regulator outlet port. Manifolds available with 3 or 5
outlets and include one outlet cap.
● Relieving diaphragm allows outlet pressure setting to
be reduced even though the system is dead-ended.
Pressure downstream of check valves will not be
reduced.
● Easily replaceable valve cartridge contains valve,
valve seat, valve spring, and filter element
● Two high pressure ports (inlet and primary gauge)
and two regulated pressure ports (outlet and
secondary gauge)
● Diametrically opposite inlet ports facilitate
manifolding for multiple dispensing applications.
Each manifolded regulator operates independently as
though attached directly to the gas supply source.
● Bonnet wrench hex same size as tank adapter - one
wrench fits both

Regulator for Soft Drink Dispensing Systems
Technical Data
Fluid: Carbon dioxide. The R81 regulator is designed for use in soft drink
dispensing systems to control cylinder gas (carbon dioxide, nitrogen, air)
pressure to the product containers. Other Norgren regulators (R84 for soft drink
carbonators, 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:
130 ± 4 psig (9.0 ± 0.28 bar)
Materials:
Body: Brass
Bonnet: Zinc
Valve cartridge: Teflon, brass, stainless steel
Diaphragm: Acetal and nitrile
Relief valve: Brass, polycarbonate, nitrile, aluminum
Seals: Nitrile
