Sensus 122-12-2 1/2 Regulator

The Sensus 122-12-2 is a field-proven industrial gas pressure regulator engineered for high-precision control in light commercial and industrial combustion systems. This 1/2 inch NPT gas regulator features a robust die-cast aluminum body designed to manage a 15 PSI maximum inlet pressure, providing the stability required for sensitive downstream components. With a precise 12" to 28" WC outlet pressure range, it is ideal for applications requiring higher-than-average delivery pressures for oversized burner manifolds or specialized utility service. The Model 122-12 series utilizes a large diaphragm area to ensure rapid response to load changes, maintaining a steady setpoint even during abrupt cycling. For technicians troubleshooting pressure drops or surging, this low pressure gas regulator offers the reliable lock-up characteristics and repeatability necessary for code-compliant HVACR installations and gas distribution maintenance.

Key Benefits for Contractors

• High-Inlet Capacity: Handles up to 15 PSI, making it suitable for high-pressure gas service drops.
• Precise Setpoints: The 12" to 28" WC spring range allows for fine-tuned calibration in complex burner systems.
• Versatile Mounting: Compact 1/2" footprint integrates easily into existing pipe runs and manifold configurations.
• Rugged Construction: Built by Sensus Gas Division to withstand mechanical stress in demanding boiler rooms and mechanical spaces.
• Optimal Regulation: Minimizes "hunting" and pressure fluctuations for consistent appliance performance.

Common Technical Questions

What is the maximum capacity of the Sensus 122-12-2?
Capacity depends on the pressure drop across the orifice; however, this 1/2" model is optimized for high-pressure industrial applications where consistent delivery of up to 28" WC is required.

Can this regulator handle natural gas and LP?
Yes, the Sensus 122 series is compatible with natural gas, propane (LPG), and other non-corrosive industrial gases, provided the internal materials are matched to the specific gravity of the medium.

Is an external vent line required?
While many configurations include an internal relief or vent limiter, local codes typically require gas regulator venting to the outdoors in indoor installations to ensure safety.
