Gas Pressure Regulators for Zero Governor Service

RZ & 21OZ

MAXIMUM INLET PRESSURES

RZ Models............................................. 1 psi (68 mbar)

210Z Models.........................................5 psi (340 mbar)

GASES: Suitable for natural, manufactured, mixed gases,

liquified petroleum gases and LP gas-air mixtures.

MOUNTING: Upright Only

NOTE: All Maxitrol regulators should be installed and

operated in accordance with Maxitrol’s “Safety Warning” Bulletin.

Z SeriesZ Series

Z Series

Z SeriesZ Series

Both the RZ and 210Z series are adaptable for air-gas mixing applications. They may be used for outlet pressures close to atmospheric, from slightly above to slightly below (-1.0” to 1.5” w.c.;

-2.5 mbar to 3.75 mbar).

Because of balanced valve construction, Z models offer superior performance at an economic price to other type atmospheric regulators.

Covenient tap locations are provided on the 210Z models, for downstream sensing, cross con-

nections, and differential control. Four locations can be tapped and plugged for measuring pressure (see back page).

Pipe sizes are consistent with standard models — 3/ 8” to 1” for the RZ series, and 1” to 4” for the 210Z series. Metric threads are also available.

Maxitrol Z model regulators are used for flow control of burners, nozzle mixers, mixing tees, and proportional premixers.
