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).
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.
