Sensus 019-01029-035 Orifice

The Sensus 019-01029-035 is a precision-engineered 5/16-inch orifice specifically designed for integration with Sensus Model 496 domestic service regulators. As a critical flow control component, this orifice regulates the volumetric flow rate of natural gas or propane, ensuring the regulator maintains a stable downstream pressure regardless of inlet fluctuations. Constructed from high-grade aluminum or brass, it resists debris erosion and chemical degradation, which is essential for maintaining the lock-up pressure integral to residential and light commercial meter sets. When performing field maintenance or capacity adjustments on the 496 series, selecting the correct orifice bore size is vital to avoid over-pressurization or pilot outages. This component ensures the internal relief valve functions within its specified curve, providing a reliable seal against the valve seat. Proper installation helps technicians achieve the precise WC (water column) discharge required for optimal burner performance.

• Precision Machined: Ensures exact 5/16" flow diameter for consistent SCFH (Standard Cubic Feet per Hour) delivery.
• Model 496 Compatibility: Engineered specifically for the Sensus 496 regulator body and valve linkage.
• Material Durability: Resists scoring and wear from pipeline contaminants, extending the service interval.
• Optimized Regulation: Facilitates tight pressure control for high-efficiency furnace and water heater applications.

Is this orifice compatible with other Sensus regulator models?
This specific 5/16" orifice is optimized for the Sensus 496. Using it in other models may affect the flow coefficient (Cv) and regulator stability.

What is the maximum inlet pressure for this 5/16" orifice?
The maximum inlet pressure depends on the specific spring range and body configuration of the 496 regulator, typically used in service pressure reductions from pounds to inches.

Does this orifice require a specific tool for installation?
A standard thin-walled socket is recommended to ensure the orifice is seated firmly without stripping the threads or damaging the precision bore.
