Itron-Actaris 757623 Orifice

The Itron-Actaris 757623 Orifice is a high-precision 1/4" dia aluminum orifice engineered specifically for technical flow regulation in series B42 and B42R gas regulators. As a veteran technician knows, selecting the correct gas regulator orifice size is non-negotiable for system safety and efficiency. This component maintains a maximum inlet pressure rating of 60 PSIG, making it a critical part for mid-range commercial and residential gas service applications. The internal gas regulator replacement part is manufactured from lightweight, corrosion-resistant aluminum to ensure long-term stability and precise BTU output regulation without the risk of scaling or premature occlusion under standard operating temperatures. Use this OEM Itron Actaris part to restore factory-spec lock-up and flow performance. When performing a field replacement, ensure you verify the loading ring position and torque the unit precisely to manufacturer requirements to prevent internal bypass or diaphragm damage. This is a direct industrial-grade solution for consistent gas flow control in demanding HVACR environments.

• Precise Flow Calibration: The 1/4 inch diameter is precision-machined to ensure exact natural gas flow rates and consistent burner pressure.
• Durable Aluminum Construction: Lightweight and resistant to oxidation, preventing debris buildup that can cause gas regulator failure.
• System Compatibility: Designed for seamless integration with Itron B42R residential regulators, maintaining a 60 PSIG max inlet pressure rating.
• Ease of Installation: Standard mechanical fitment allows for straightforward field swaps during routine HVAC maintenance.

• How do I determine if a 1/4" orifice is the correct size for my regulator? Orifice sizing is determined by the specific BTU load and required inlet-to-outlet pressure drop. Reference the Itron B42 capacity tables to confirm the 757623 part number matches your performance requirements.
• Can this orifice be used for Propane as well as Natural Gas? While the material is compatible, the gas orifice flow coefficient differs between gases. Always consult the specific conversion charts for your regulator model before switching fuel types.
• What are the signs of a failing or clogged orifice? Common symptoms include low burner pressure, uneven flame patterns, and the inability of the regulator to reach its set point pressure.
