(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
