ROOTS B34 Series commercial gas regulator, formerly Itron B34, for industrial pressure control

B34 Series Commercial and Industrial Gas Regulator

The B34 Series gas regulator represents ROOTS Regulators‘ commitment to continuing Itron’s legacy of excellence in pressure control technology. Following Dresser Utility Solutions’ acquisition of Itron’s gas regulator business, the B34 maintains its reputation for reliability while advancing under the ROOTS brand name in North America.

This commercial and industrial regulator excels in applications requiring quick response to variable loads. Its robust design and precision engineering make it particularly effective for gas engines, burners, furnaces, and boilers where consistent pressure control is critical for operational safety and efficiency.
