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 economic price to other types of atmospheric regulators. Maxitrol’s RZ and 210Z Zero Governor model regulators are used for flow control of burners, nozzel mixers, mixing tees and proportional premixers.

Specifications:

• 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. flange (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.
