Sensus 122-12-1 1/2 Regulator

Professional-grade gas pressure management requires the precision found in the Sensus 122-12-1 1/2" Regulator. Engineered by the Sensus Gas Division, this industrial-duty regulator is optimized for commercial and light industrial applications where stable outlet pressure is non-negotiable. With a 1/2 inch NPT connection and a 15 PSI maximum inlet pressure rating, this unit is built to manage high-demand gas distribution systems and appliance manifolds. The fixed orifice (12/28") design ensures consistent regulation across varying flow rates, eliminating the volatility often associated with inferior components. For contractors servicing multi-family residential or commercial kitchens, this low-pressure gas regulator provides the necessary lock-up characteristics and sensitivity to protect sensitive downstream equipment. Its rugged construction and field-proven reliability make it a standard choice for HVACR technicians replacing obsolete or failing gas valves in the field.

Key Technician Benefits

• Compact Footprint: The 1/2" NPT size allows for easy installation in tight furnace cabinets or meter sets.
• Sensus Gas Division Quality: Built to meet strict utility-grade standards for gas safety and performance.
• Versatile Media Compatibility: Ideal for natural gas, LP vapor, and other non-corrosive technical gases.

Common Technical Questions

Is the Sensus 122-12-1 suitable for outdoor use?
Yes, Sensus 122 series regulators are designed to withstand environmental exposure, provided they are installed with the vent pointing downward or protected by a weather-resistant vent cap to prevent moisture ingress.

Can I use this regulator for propane applications?
This model is compatible with LP vapor. However, technicians must verify that the 12/28" fixed orifice and the factory-set spring range match the specific BTU requirements of the propane appliance.

What is the purpose of the fixed orifice in this model?
The fixed 12/28" orifice is engineered to provide a specific flow capacity and response time, ensuring the regulator does not hunt or oscillate during rapid changes in gas demand.
