Itron B42 The B42 service regulator incorporates a molded diaphragm and increased lever ratio into a conventionally designed regulator. The result is a lighter, more compact unit that provides the power, capacity, and relief performance of much larger regulators. Reduced weight means easier handling and installation. Reduced size means easier installation in limited spaces and a lower profile meter set. 

Typical applications include residential services, 2 PSIG systems, and small commercial services. Application: Residential & Light Commercial Measurement range: 2000 SCFH Operating pressures: IN. WC. - 5 PSIG Max Inlet Pressure Rating: 125 PSIG Connection

Itron B38 The B38 service regulator is designed for use on large commercial and industrial loads. Large orifices are available (up to 1 3/8") for high capacity/low inlet pressure applications.

 An added feature of the B38R is its massive relief capacity. All choke points in the relief flow path are enlarged to ensure a minimum pressure build-up in the event of regulator failure. The need for external relief valves for full capacity relief is eliminated in most applications. 

Application: Large Commercial & Industrial Measurement range: 20000 SCFH Operating pressures: IN. WC. - 5 PSIG Max Inlet Pressure Rating: 125 PSIG Connection Size(s): 1-1/2", 2", 2"FL, & 3"FL

Itron B531 The B531 is designed for light to medium commercial applications where the added safety of twin sliding orifices and/or dual relief is desirable. The IM version can perform all of the functions of a conventional monitor set in a single device. Small diaphragm cases allow the B531 to respond quickly to fast on/off loads. 












Typical applications include schools, day care centers, nursing homes, and high-traffic areas such as drive-thru restaurants and car washes. 

Application: Commercial & Light Industrial Measurement range: 5000 SCFH Operating pressures: IN. WC. - 5 PSIG Max Inlet Pressure Rating: 125 PSIG Connection Size(s): Inlet: 3/4", 1", & 1-1/4" Outlet: 3/4", 1", 1-1/4", 1-1/2", & 2"

Itron B838 The B838 is designed for large commercial and industrial applications where the added safety of twin sliding orifices and/or dual relief is desirable. The increased capacity inherent in parallel flow regulators enables the B838 to handle large loads even at delivery pressures of 2 and 5 PSIG. The 838 can thus address fixed factor needs while retaining all of the favorable characteristics of spring loaded regulators such as quick response, low lockup, and internal relief. 

Typical applications include hospitals, apartment buildings, hotels, high-rises, and public buildings. 














Application: Large Commercial & Industrial Measurement range: 50000 SCFH Operating pressures: IN. WC. - 5 PSIG Max Inlet Pressure Rating: 125 PSIG Connection Size(s): 2 x 2", 2 x 3"FL, 2 x 4"FL
