Itron-Actaris B34R-2 Regulator

The Itron-Actaris B34R-2 gas regulator is a field-proven solution for residential and light commercial applications requiring precise pressure regulation. This specific configuration features a 2" NPT internal relief valve (IRV) body with a 7/8" x 1" orifice, engineered to handle consistent flow rates while maintaining tight lock-up characteristics. Designed with a 6.5-13" w.c. spring, this unit is ideal for natural gas pressure regulation where a stable outlet pressure is critical for downstream equipment performance. The B34R series is known among technicians for its robust diaphragm case and versatile mounting positions, allowing for easier retrofits in tight mechanical spaces. By utilizing high-grade internal components, the B34R-2 regulator minimizes droop and ensures reliable performance under varying inlet pressures, making it a standard choice for HVAC contractors prioritizing system uptime and safety.

Key Benefits:

• Large 2-inch IRV body provides high-capacity relief and simplified piping for commercial gas services.
• Optimized 7/8" x 1" orifice sizing ensures superior flow control and stability across the entire gas pressure range.
• Adjustable 6.5" to 13" water column spring allows for precise field tuning to meet specific appliance requirements.
• Rugged construction minimizes vibration-induced wear, ensuring long-term reliability in outdoor installations.
• Internal relief mechanism reduces the need for additional vent piping, streamlining the installation process for field technicians.

Common Questions:

How do you adjust the outlet pressure on the B34R-2?
Pressure adjustments are made by removing the seal cap and turning the adjustment screw on the spring tower. Always use a calibrated manometer to verify that the outlet pressure matches the 6.5-13" w.c. range required for your specific equipment.

Can this regulator be mounted in any orientation?
While the Itron B34R supports multiple positions, the vent must always be pointed downward or protected from the elements to prevent moisture and debris from entering the diaphragm case, which could cause regulator failure.

What is the purpose of the internal relief valve (IRV) in this model?
The IRV acts as a safety feature that vents excess pressure to the atmosphere if an over-pressure condition occurs, protecting downstream HVAC valves and residential appliances from damage.
