Itron-Actaris B42R-1 Regulator

The Itron-Actaris B42R-1 Regulator is a spring-loaded, self-operated unit engineered for precise pressure control in residential and light commercial gas service. This specific configuration features a 1" NPT connection, a 1/2" x 9/16" interchangeable aluminum orifice, and a Dark Green spring calibrated for an outlet pressure range of 6-16" w.c. As a veteran-grade component, the B42R-1 is the direct replacement for B42R-1-BLUE, ensuring seamless field swaps without piping modifications. Its internal relief valve (IRV) and 1" threaded vent provide exceptional overpressure protection, while the 6:1 lever ratio and molded deep convolution diaphragm deliver a true bubble-tight lock-up. Designed to handle up to 125 PSIG inlet pressure, this regulator balances a compact footprint with the high-capacity performance typically reserved for larger industrial bodies.

• Versatile Compatibility: Direct drop-in replacement for the discontinued B42R-1-BLUE model.
• Enhanced Safety: Integrated 1" internal relief valve (IRV) provides superior overpressure protection.
• Field Serviceable: Features an interchangeable adjustment spring and aluminum orifice for rapid site-specific tuning.
• Reliable Construction: Molded deep convolution diaphragm with an O-ring seal ensures consistent performance and long service life.
• Precise Control: Plated steel 6:1 lever ratio offers high sensitivity to downstream pressure demands.

What is the difference between the B42R-1 and the B42R-1-BLUE?
The B42R-1 is the current production model and serves as the direct functional and dimensional replacement for the older B42R-1-BLUE version.

Can I change the outlet pressure range in the field?
Yes, the internal adjustment spring is field-interchangeable; however, this specific unit is factory-equipped with the Dark Green spring for the 6-16" w.c. range.

Is this regulator suitable for propane or only natural gas?
While commonly used for natural gas, the B42 series is compatible with other gases, including propane, provided you apply the appropriate correction factors to the capacity tables.
