Itron-Actaris B42R-3/4 Regulator
The Itron-Actaris B42R-3/4 Regulator is a spring-loaded, self-operated gas pressure regulator engineered for precision in residential and light commercial HVAC system applications. Featuring a 3/4" NPT connection and an internal relief (IRV) valve, this model ensures high-capacity relief performance without the need for additional overpressure protection. The 6:1 lever ratio and 12.6 sq. in. molded deep convolution diaphragm provide a consistent lock-up pressure and stable regulation even under fluctuating inlet conditions. Equipped with a 1/2" x 9/16" orifice and a dark green spring, it maintains an adjustable outlet range of 6-16" w.c. with a maximum inlet pressure of up to 125 PSIG. The cast iron valve body and 1" threaded vent with stainless steel screen ensure durability for veteran HVAC contractors requiring reliable natural gas service equipment. This Itron B42R model is a compact solution that matches the performance of significantly larger units, optimizing space in commercial HVAC meter sets.
Key Benefits for Technicians:- Internal Relief Valve (IRV): Provides high-capacity overpressure protection through a 1" vent, simplifying gas piping layouts.
- Molded Diaphragm Design: Deep convolution with an O-ring seal ensures a bubble-tight lock-up and long-term sensitivity.
- Interchangeable Parts: Features a field-interchangeable dark green spring and aluminum orifice for rapid adjustment to site-specific BTU loads.
- Heavy-Duty Construction: High-tensile strength ASTM A-126 cast iron body stands up to rugged field installations.
- Compact Footprint: Superior 6:1 mechanical advantage allows for a smaller housing while maintaining high-volume gas flow.
What is the relief capacity of the B42R compared to the B42N?
The B42R features a dedicated internal relief mechanism and a 1" vent specifically for safety shutoff and relief scenarios. The B42N is a non-relief version typically used where external relief or low inlet pressures are present.
Can I use this regulator for propane (LPG) service?
While commonly used for natural gas, the B42 series can be used for other gases (like LPG) by applying the appropriate specific gravity conversion factors to the flow rate tables. Always verify the spring range matches your target manifold pressure.
Is the dark green spring compatible with higher pressures?
This specific model is configured for a 6-16" w.c. range (Dark Green 762117). If your application requires pounds-to-pounds regulation, you must consult the Itron B42HP high-pressure series spring charts, as springs are not interchangeable between standard and HP bodies.
