210 Series balanced valve design is a lockup-type regulator. A balanced valve design maintains steady outlet pressure control with widely varying inlet pressures. As a result, the 210 Series provides precise regulation over a wide range of pressures and flow rates. Applications include gas-fired boilers, steam generators, industrial furnaces, and ovens. In addition, a remote sensing option is available on the 210D, E, and G models. They are suitable for natural, manufactured, mixed gases, liquefied petroleum gases, LP gas-air mixtures, and gases of DIN EN 437 gas families 1, 2, and 3.
