Daikin-McQuay 0151R00273S TXV-FX-3T Adjustable Thermostatic Expansion Valve 3-Ton R-32

The Daikin-McQuay 0151R00273S is a genuine OEM adjustable thermostatic expansion valve (TXV) designed for 3-ton HVAC systems operating on R-32 refrigerant. Purpose-built as a direct-fit replacement for compatible Daikin and McQuay equipment, this valve restores precise refrigerant metering and ensures the system performs to its original design specifications.

A thermostatic expansion valve regulates the flow of refrigerant into the evaporator coil based on superheat conditions at the evaporator outlet. By maintaining optimal superheat, the TXV maximizes system efficiency, protects the compressor from liquid slugging, and ensures consistent cooling capacity across varying load conditions.

Key Features:

• Genuine OEM Daikin-McQuay replacement part — MPN 0151R00273S
• Adjustable superheat setting for fine-tuned system performance
• Rated for 3-ton nominal capacity applications
• Compatible with R-32 refrigerant
• Versatile mounting — can be installed in any orientation on the evaporator coil inlet
• Engineered for compatibility with Daikin-McQuay residential and light commercial HVAC systems
• Factory calibrated to meet original equipment performance standards

Using a genuine Daikin-McQuay replacement TXV ensures the valve is calibrated to the system's original design specifications, helping to maintain peak efficiency, reduce the risk of callbacks, and extend the operational life of the overall HVAC system.
