🛠️ HVAC Depot Pro Tip

When replacing a TXV, do not select the valve based on tonnage alone.

For this valve, verify these primary identifiers:

Cat #: Y8735
Part #: RFGF05E-2.5-796
System Capacity: 1.5–2.5 Ton
Refrigerant: R-410A

Before installation, also verify:

  • Indoor evaporator coil model
  • Outdoor condenser or heat pump model
  • R-410A refrigerant
  • Required TXV capacity
  • Existing TXV part number
  • Inlet and outlet connection sizes
  • Equalizer configuration
  • Distributor configuration
  • Manufacturer charging specifications

Using the correct TXV is important for maintaining proper refrigerant flow and system superheat.

  • 1.5-ton R-410A systems

  • Central air conditioning systems
  • Heat pump systems
  • Indoor evaporator coils
  • Select Lennox-family HVAC equipment requiring this TXV

Always verify the complete indoor and outdoor equipment model numbers before ordering.
