RZ and 210Z

Zero Pressure Regulator Design

210DZ… RZ and 210Z Series

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 Pressure Regulator models are used for flow control of burners, nozzel mixers, mixing tees and propor­tional premixers.
