Product Details

The Lennox 42W30 is a thermostatic expansion valve (TXV) designed for residential and light commercial air conditioning and heat pump systems using R410A refrigerant. This precision metering device regulates refrigerant flow into the evaporator coil, ensuring optimal system performance and efficiency for 4-ton capacity systems.

Key Specifications:

  • Refrigerant Type: R410A
  • Capacity Rating: 4 ton
  • Inlet Connection: 3/8 inch ODF (flare)
  • Outlet Connection: 1/2 inch ODF (flare)
  • OEM Lennox replacement component
  • Factory-calibrated for precise superheat control

This TXV maintains proper refrigerant superheat by automatically adjusting refrigerant flow based on evaporator load conditions. The valve helps prevent liquid refrigerant from returning to the compressor while maximizing cooling capacity and system efficiency. Designed as a direct OEM replacement for Lennox HVAC equipment, ensuring proper fit and reliable operation.

Haven't ordered from here since 2010. Only 2 orders overall and it was actually pretty great thank you. Though I will say, the item selection has gone way down but I still was very satisfied. Thanks again.

I found the best price for Bosch rear wiper blade. It was shipped quick with da seamless delivery. THMotorsports is my new go to. Thank you to Joy .
