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 suffix letter R to model number when ordering. Minimum Regulation..................R400Z Suitable for pilot flow 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. Maxitrols RZ and 210Z Zero Governor model regulators are used for flow control of burners nozzel mixers mixing tees and proportional premixers. 210EZ RZ and 210Z Zero Governor Design Specifications
