Itron-Actaris B31R-3/4 Regulator
The Itron-Actaris B31R-3/4 Regulator is a job-site standard for light commercial and industrial natural gas distribution. Engineered for utility service regulation and furnace gas pressure control, this model features a 3/4" NPT valve body constructed from high-tensile cast iron. The internal 1/2" orifice is paired with a gray spring (part number 762121), providing a stable outlet pressure range of 4 to 9 inches Water Column (w.c.).
Designed with a 27-square-inch diaphragm and a powerful lever ratio, the B31R ensures fast response protection against shock damage in systems with sudden on/off loads. The "R" designation confirms the inclusion of a 3/4" internal relief valve (IRV), offering critical overpressure protection by venting gas safely if the seat fails to close due to debris or rapid shut-off spikes. This regulator is suitable for service loads up to 6,700 SCFH and maintains precise downstream regulation despite varying inlet pressures up to 125 PSIG.
Key Benefits
- Internal Relief Valve (IRV): Provides superior overpressure protection to prevent equipment damage during unexpected pressure spikes.
- High Flow Capacity: Large diaphragm area allows for consistent performance in medium-sized boilers and industrial heating applications.
- Durable Construction: Features a rugged cast iron body and a stainless steel vent screen to resist environmental wear.
- Field-Interchangeable Components: Simplifies maintenance with an interchangeable orifice and adjustment springs for varying task requirements.
- Shock Protection: Rapid actuation makes it ideal for systems with high-cycling solenoid valves or rapid-fire burners.
Common Questions
Can the B31R be installed in any orientation?
Yes, the diaphragm casing can be rotated 360 degrees relative to the body. However, for outdoor installations, the regulator vent must point downward to prevent moisture, ice, or debris from obstructing the relief path.
What is the maximum inlet pressure for this configuration?
With the 1/2" orifice, the maximum allowable operating pressure (MAOP) is typically rated for 125 PSIG, though actual capacity depends on your specific outlet pressure set point and flow requirements.
Does this model require a strainer?
While not integrated, installing a strainer on the inlet side is highly recommended for commercial gas regulators to prevent debris from lodging in the Buna-N valve seat and causing lockout failure.
