Sensus 019-01029-005 Orifice

The Sensus 019-01029-005 is a precision-engineered 1/2 inch orifice specifically designed for the Sensus 496 gas regulator. This OEM component is critical for gas pressure regulation in residential, light commercial, and small industrial service applications. As a veteran-grade replacement part, it enables the 496 series to manage a maximum inlet pressure of up to 20 psig while maintaining stable downstream delivery. Constructed from high-grade aluminum, this orifice for 496 regulator ensures long-term resistance to corrosion and consistent flow geometry for various media, including natural gas, propane, air, and nitrogen.

When performing field maintenance or recalibrating a domestic service regulator, selecting the correct orifice diameter is essential to match the specific capacity requirements of the burner or furnace. This 1/2-inch gas regulator part integrates seamlessly with the 496’s 4-inch roll-out diaphragm, providing the high-flow performance typically associated with larger 6-inch diaphragm units. Technicians should verify that the Sensus 019-01029-005 is paired with the appropriate load spring (e.g., silver, blue, or green) to achieve the target outlet pressure set point. This part ensures positive dead-end lockup and maintains the integrity of the internal relief valve (IRV) system, provided the vent is correctly oriented in the field.

• Optimized Flow Stability: Specifically machined to the 1/2-inch specification to ensure laminar flow and precise gas pressure control for stable burner operation.
• Broad Media Compatibility: Engineered for safe use with natural gas, LP gas, carbon dioxide, and dry nitrogen in commercial and industrial piping.
• Precision Fitment: Genuine Sensus OEM part prevents bypass leakage and simplifies the orifice replacement process during routine regulator servicing.
• Enhanced Capacity: Allows the compact Model 496 to deliver higher volume throughput compared to standard residential orifices.

What is the maximum inlet pressure for this 1/2-inch orifice?
When installed in a Sensus 496 regulator, the 1/2-inch orifice (019-01029-005) is rated for a maximum inlet pressure of 20 psig to ensure optimal performance and safety.

Is this part compatible with other Sensus regulator models?
While Sensus uses similar numbering across ranges, the 019-01029 series is specifically designed for the 496/043 model series. Always refer to your specific regulator’s technical datasheet to confirm the correct cross-reference.

Does this orifice include the valve seat?
This part number refers to the 1/2" aluminum orifice itself. The valve seat is typically a separate component within the valve body assembly of the 496 regulator; however, the orifice provides the critical sealing surface for the seat disc.
