ManualsBrandsMaxitrol ManualsBalanced Valve Regulators1" Gas Appliance Regulator (1,400,000 BTU) (1" Max Inlet)

Pipe Sizes ..................................... 3/8” to 1” threaded connections with NPT or ISO7-1 threads.

Housing Material ......................... R400(S), R500(S), R600(S): aluminum.

Mounting ..................................... Suitable for multi-positional mounting. If a

is installed,

mount in an upright position only. The

12A06 is multi-positional.

NOTE: All Maxitrol gas pressure regulators should be installed and operated in accordance

with Maxitrol Safety Warning Instructions (see GPR_MI_EN.ES or GPR_CSA_MI_EN.FR).

Certications ..................................R400(S), R500(S), R600(S): ANSI Z21.18/CSA 6.3 Gas Appliance Pressure Regulators.

Gas Types ........................................ Suitable for natural, manufactured, mixed gases, liqueed petroleum gases, and LP

gas-air mixtures.

Rated Inlet Pressure ........................CSA Certied: R400(S), R500(S), R600(S): 1/2 psi (3.4 kPa)

Maxitrol Tested: ..............................R400, R500, R600: 1 psi (6.9 kPa);

R400S, R500S, R600S: 5 psi (34.5 kPa)

Emergency Exposure Limits ............R400, R500, R600: 2 psi (13.8 kPa)

R400S, R500S, R600S: 12.5 psi (86.2)

Ambient Temperature Ranges ........ R400(S), R500(S), R600(S): -40° to 205°F (-40° to 96°C)

Zero Governor Models ...................Please refer to pages 32-37 for RZ model information.

Minimum Regulation .................... Suitable for pilot ow applications. (Circle P) (0.15 CFH NG), None (1.5 CFH NG).

Model Designations ......................(F) Factory-set; xed non-adjustable regulator.

(M) B.S.P. - PL parallel thread - conforms to ISO 701, where pressure tight joints are made

on the threads.

NOTE: These R/RS regulators are not suitable for dead-end lockup service. They are capable of controlling pressure at very

low ows such as standing pilots, but should not be used as a line pressure regulator for appliances equipped with

electronic ignition unless the automatic control valve can open against line pressure.

The R & RS series’ double diaphragm balanced valve design

makes it possible to maintain steady outlet pressure control

with widely varying inlet pressures. The regulator is physically

small yet has exceptional capacity characteristics. R & RS series

regulators are intended for use with both main burner and pilot

load applications. They are ideally suited for use with infrared

heaters and pilot lines on large industrial heaters and boilers.
