Daikin-McQuay 0151R00275 TXV-FX-5T Adjustable Thermal Expansion Valve 5-Ton OEM

The Daikin-McQuay 0151R00275 is a factory-new, OEM adjustable thermostatic expansion valve (TXV) designed for 5-ton HVAC system applications. Part of the FX-series valve lineup, this adjustable TXV provides precise superheat control and reliable refrigerant flow regulation in Daikin-McQuay residential and light commercial air conditioning systems.

A thermostatic expansion valve is a critical refrigeration circuit component that meters refrigerant flow into the evaporator coil based on real-time temperature and pressure conditions at the evaporator outlet. The adjustable design allows field technicians to fine-tune superheat settings to match system requirements and optimize efficiency.

Key Features:

• OEM Daikin-McQuay replacement part — direct fit for compatible 5-ton systems
• Adjustable superheat setting for precise refrigerant flow control
• Regulates refrigerant entering the evaporator coil based on temperature and suction pressure
• Maintains stable cooling performance and consistent heat absorption
• Factory new condition with 1-year manufacturer warranty
• Also referenced as part number 0151R00275S

This valve is the correct OEM replacement for Daikin-McQuay systems requiring a 5-ton FX-series adjustable TXV. Installation should be performed by a certified HVAC technician, including proper refrigerant recovery, nitrogen-purge brazing, sensing bulb placement on the suction line, and system leak testing prior to recharge.
