R700
The new R700 is the answer for applications requiring a 1 or 1–1/4” NPT (ISO7‑1) appliance regulator with high capacity at a lower cost. The balanced valve design delivers the same exceptional performance found in Maxitrol’s R/RS Series regulators. The valve maintains a steady outlet pressure over a wide range of inlet pressures and flow rates.
R700 regulators are ideally suited for main burner and modulated burner applications. Typical applications are furnaces, industrial heaters, and boilers.
The R700 is a lockup type regulator. Under no flow conditions, outlet pressure will rise above adjusted set pressure but will not rise to line pressure.
R700Z
The R700Z zero governor regulators are designed as control valves in air-gas mixing applications. The valve is used in premix burners, nozzle mixers, tee mixers, and proportional premixers. The control is supplied with an integral adjustable bypass for precise minimum flows in high turndown applications. Its design maintains a steady regulated control pressure over a wide range of flow rates.
