B31 Series

B31 Light Commercial Natural Gas Regulator

The high-performance B31 regulator has a sizeable operative diaphragm area and a powerful lever ratio. The Itron B31 maintains proper regulation over a wide flow range on systems with extreme differences in inlet pressure to deliver high capacities with low inlet pressures. The service regulator applications include demanding residential and light commercial services.

Itron's residential or light commercial gas regulators are lightweight and solidly constructed for reliable daily operation. The gas regulators are easy to install and come in many mounting configurations and inlet/outlet sizes to accommodate a variety of needs.

The Itron B31 is used in utility services and small-to-medium sized furnaces and boilers where inches of water column or pounds delivery is desired. The rapid response of the B31 is particularly well suited for applications where sudden on/off loads could cause shock problems.
