Sensus 143-62-023-43 Orifice

Engineered for high-performance pressure regulation, the Sensus 143-62-023-43 5/16" Orifice is a critical metered flow component designed specifically for the Sensus 143-80 gas pressure regulator series. This replacement regulator orifice is precision-machined from high-grade aluminum to ensure exact seat alignment and consistent flow coefficients within sensitive gas delivery systems. In the field, techs rely on this 5/16-inch orifice to handle a maximum inlet pressure of up to 40 psig, making it a "go-to" for technicians balancing capacity and safety in residential or light commercial footprints.

The Sensus 143-62-023-43 ensures stable lock-up performance and reduces the risk of pilot fluctuations or over-pressurization. This natural gas regulator part is fully compatible with 143-80, 143-80-2, and 143-80-6 models, providing the necessary mechanical interface for the internal relief valve (IRV) to function within its designated performance curve. Its robust aluminum construction resists common corrosive elements found in gas streams, extending the service life of the Sensus 143 series orifice during extreme temperature shifts from -20°F to 150°F.

• Optimized Flow Control: Specifically sized at 5/16" to maintain stable outlet pressure for the 143-80 regulator series.
• High Pressure Rating: Safely supports inlet pressures up to 40 psig without compromising diaphragm integrity.
• Verified Compatibility: Direct OEM replacement for Sensus 143-62-023-43, fitting Rockwell, Equimeter, and Invensys legacy models.
• Simplified Service: Designed for rapid installation via the regulator's union nut connection, allowing for quick field swaps.

• What is the maximum inlet pressure for this 5/16" orifice? This specific part is rated for a maximum of 40 psig. For higher inlet pressures, a smaller orifice size (e.g., 1/8" or 3/16") may be required.
• Is this orifice compatible with propane (LPG) applications? Yes, when used within a properly configured Sensus 143 regulator, it can handle natural gas, LPG, nitrogen, and dry CO2.
• Does this include the valve seat? This part number is for the aluminum orifice only; the one-piece molded Buna-N valve seat is typically a separate component of the valve stem assembly.
