210 Series balanced valve design is a lockup-type regulator. Its intended applications include gas-fired boilers, steam generators, industrial furnaces, and ovens. Remote sensing option is available on 210D, E, and G models. The 210 series is a lockup type regulator. The balanced valve design makes it possible to maintain steady outlet pressure control with widely varying inlet pressures. The regulator has an integrated dampening mechanism in the breather outlet and the sensing tube to improve regulating stability and reduce hunting tendencies. 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.
