Pipe Sizes .................................. RZ Models: 3/8” to 1” threaded connections with NPT or ISO7-1 threads.
210Z Models: 1” to 3” threaded connections with NPT or ISO7-1 threads.
4” 125 lb. ange (210JZ only).
Housing Material ......................R400Z, R500Z, R600Z, 210DZ, 210EZ, 210GZ, 210JZ: aluminum.
Mounting ..................................R400Z, 210DZ, 210EZ, 210GZ, 210JZ mount in an upright position only. R500Z, R600Z
suitable for multi-positional mounting. If ball check vent limiting device is installed, mount in
an upright position only.
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).
Certications ..............................R400Z, R500Z, 210DZ, 210EZ, 210GZ: ANSI Z21.18/CSA 6.3 Gas Appliance Pressure Regulators.
Gas Types .................................... Suitable for natural, manufactured, mixed gases, liqueed petroleum gases, and LP gas-air
mixtures.
Maximum Inlet Pressure ............. CSA Certied: R400Z, R500Z: 1/2 psi (3.4 kPa); 210DZ, 210EZ, 210GZ: 5 psi (34.5 kPa)
Maxitrol Tested: R600Z: 1/2 psi (3.4 kPa); 210JZ: 5 psi (34.5)
Emergency Exposure Limits ........R400Z, R500Z, R600Z: 2 psi (13.8 kPa)
210DZ, 210EZ, 210GZ, 210JZ: 25 psi (172 kPa)
Ambient Temperature Ranges .....R400Z, R600Z: -40° to 205°F (-40° to 96°C)
R500Z: 32° to 205°F (0° to 96°C)
210DZ, 210EZ, 210GZ, 210JZ: -40° to 200°F (-40° to 93°C)
Sensing Taps ..................................210Z Models have convenient tap locations available for downstream sensing, cross connections,
and differential control. Four locations can be tapped and plugged for measuring pressure.
Remote Sensing .........................210DZ, 210EZ, 210GZ models may be ordered with remote sensing. The internal sensing
tube is omitted and external sensing taps are provided. Add sufx letter “R” to model number
when ordering.
Minimum Regulation .................R400Z: Suitable for pilot ow applications. (Circle P) (0.15 CFH NG), R500Z, R600Z: 10
CFH.
Both the RZ and 210Z series are adaptable for air-gas mixing
applications. Because of the balanced valve construction,
Z-models offer superior performance at an economical price
compared with other types of atmospheric regulators.
Maxitrol’s RZ and 210Z Zero Governor model regulators are
used for ow control of burners, nozzel mixers, mixing tees and
proportional premixers.
