Sensus 143-IRV-3/4X1 Regulator
The Sensus 143-IRV-3/4X1 is a field-proven domestic service gas regulator engineered for precision in residential and light commercial applications. This specific configuration features a 3/4" x 1" NPT straight-body connection and a 3/8" stainless steel orifice, designed to handle moderate flow requirements while maintaining stable outlet pressures. Equipped with a Green Spring, the unit provides a reliable 6" to 14" w.c. outlet pressure range, making it a staple for technicians servicing furnaces, boilers, and unit heaters. The integrated internal relief valve (IRV) delivers essential overpressure protection by venting excess pressure, typically set to activate at 7–10" w.c. above the normal set point. Built with a rugged cast iron body and a die-cast aluminum spring case, this natural gas regulator is also compatible with LP gas, propane, and air. Its versatile design allows for 360-degree rotation of the diaphragm case, simplifying installation in tight mechanical rooms or complex piping layouts.
Key Benefits for the Jobsite- Flexible Mounting: The union nut connection allows for 360-degree rotation of the diaphragm case, adapting to any piping orientation.
- Corrosion Resistance: Features a chromate conversion coating and enamel topcoat to withstand harsh environmental conditions.
- Technical Precision: The 3/8" orifice provides a balance of high capacity and lock-up performance under varying inlet pressures.
- Serviceability: Designed for easy inspection with a removable valve and orifice, reducing downtime during routine maintenance.
- What is the maximum inlet pressure for this 3/8" orifice model? The Sensus 143-80-2 with a 3/8" orifice typically supports a maximum inlet pressure of 40 PSIG.
- Can this regulator be used for propane service? Yes, the 143-IRV performs exceptionally well with natural gas, LP gas, nitrogen, and dry CO2 when proper correction factors are applied.
- Is the 1" NPT vent required to be piped away? For indoor installations, the 1" NPT vent must be piped to the outdoors to ensure safe discharge from the internal relief valve.
