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.
