Sensus 143-16-023-00 Orifice

The Sensus 143-16-023-00 is a high-precision 1/2" orifice specifically engineered for the Sensus 243 service regulator series. Built to handle the rigorous demands of commercial and industrial gas regulation, this brass orifice provides accurate flow control with a 10-degree valve angle design. It is fully compatible with both the Sensus 243-8 and 243-12 models, ensuring seamless integration during field maintenance or capacity adjustments. By utilizing a 1/2-inch port, contractors can achieve consistent natural gas flow measurement and lock-up performance across a wide range of inlet pressures. This genuine Sensus replacement part is critical for technicians managing boiler sets, furnaces, and large-scale metering applications where pressure stability is non-negotiable. Designed for durability in non-corrosive gas environments, including LPG and dry CO2, the 143-16-023-00 maintains tight tolerances to prevent droop and ensure the reliability of gas pressure regulators in high-capacity distribution networks.

• Precision Flow Control: Specifically designed for the Sensus 243 architecture to provide linear regulation and stable lock-up.
• Rugged Construction: Machined from high-grade brass to resist wear and corrosion in demanding HVACR environments.
• Interchangeable Design: Allows for rapid field changes to the orifice size, enabling easy capacity modification without replacing the entire regulator body.
• Optimized Valve Geometry: Features a 10° valve angle to improve seat-to-orifice alignment and minimize mechanical wear.

Is the Sensus 143-16-023-00 compatible with the 243-RPC pilot-operated model?
Yes, this 1/2" orifice is used across the 243 series, including pilot-operated regulators and standard 243-8 or 243-12 units, provided the technical specifications for the specific load match a 1/2-inch port.

What is the maximum inlet pressure for a 243 regulator using this 1/2" orifice?
While the regulator body may handle higher pressures, a Sensus 243-12 equipped with a 1/2" orifice typically has a maximum recommended inlet pressure of up to 125 psi depending on the specific spring and setpoint configurations.

Can I use this orifice for propane applications?
The Sensus 143-16-023-00 is suitable for natural gas, air, propane, butane, and other non-corrosive gases used in industrial combustion systems.
