Sensus 143-16-023-02 Orifice

The Sensus 143-16-023-02 Orifice is a precision-engineered 1-inch component specifically designed for use within the Sensus 243 service regulator series. Built to handle commercial and industrial gas pressure regulation, this 1-inch orifice plays a critical role in determining the flow capacity and discharge characteristics of the regulator assembly. When performing field installations or utility maintenance, selecting the correct Sensus 243-12-2 or 243-8-2 orifice size is essential to prevent hunting and ensure stable downstream pressure. This specific part is machined from high-grade materials to resist erosion under high-velocity gas flows, maintaining the Sensus orifice flow rate accuracy over extended service intervals. For technicians troubleshooting capacity issues or retrofitting existing gas pressure regulators, this 243-series orifice ensures mechanical compatibility and repeatable lock-up performance. Proper torqueing during installation is required to maintain the integrity of the valve seat and prevent internal bypass leaks in the Sensus 143-16-023-02 assembly.

Technical Specifications & Benefits

• Direct Compatibility: Engineered specifically for the Sensus model 243 series regulators to ensure a perfect mechanical fit.
• Precision Machined: The 1-inch diameter is calibrated for specific flow coefficients (Cv) required in high-capacity gas delivery.
• Durable Construction: Resistant to wire-drawing and particulate abrasion, extending the service life of the valve seat.
• Stable Regulation: Helps maintain a consistent droop profile across varying inlet pressures.

Common Installation Questions

How do I determine the flow capacity of the 143-16-023-02 orifice?
Capacity depends on the inlet pressure and the specific spring range of the 243 regulator. Reference the Sensus capacity tables for the 1-inch orifice size to ensure the BTU load requirements are met without over-sizing.

Can this orifice be used in other Sensus regulator bodies?
This specific part number is designed for the 243 series. While some Sensus parts share dimensions, using this in a non-specified body may lead to seat misalignment or improper shut-off.

Is any special tooling required for replacement?
A standard orifice wrench or deep-well socket is recommended to ensure the part is seated squarely without damaging the precision-machined edges.
