Maxitrol's New R700 High-Capacity Appliance Regulator

Maxitrol's New R700 High-Capacity Appliance Regulator


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.


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.
