Product Details

The Carrier 340620-734 TXV Kit is a genuine OEM replacement thermostatic expansion valve assembly designed for use in Carrier residential and commercial HVAC systems. Also known as a thermal expansion valve or TEV, the TXV is a critical refrigerant-side component that meters and regulates the flow of refrigerant entering the evaporator coil, maintaining proper superheat levels for optimal system efficiency and consistent cooling performance.

Key Features:

  • Genuine Carrier OEM part — engineered to original factory specifications
  • Regulates refrigerant flow into the evaporator coil for precise pressure and temperature control
  • Helps restore system efficiency and prevent refrigerant flooding or starvation
  • Direct-fit replacement for compatible Carrier, Bryant, and Payne HVAC models
  • Supports reliable, long-term system operation when installed correctly

The Carrier 340620-734 TXV Kit is part of Carrier's 340620-series expansion valve replacement line. As a factory-authorized component, it ensures seamless integration with compatible systems and upholds manufacturer performance standards. This kit includes the thermostatic expansion valve assembly needed to restore proper refrigerant metering in the system.

All went well

Great price Excellent service Fast delivery

'Ordered lug nuts for my new wheels-shipping was fast and the price was good. Everything arrived as expected and worked well. Smooth overall experience.'

fast shipping great prices thanks

Tires in the add show studded tires but what I received was studdless tires . Will talk to THM Motorsport after this. But price was great

THMOTORSPORTS responded and shipped my purchases of Auxbeam products very quickly. When received, everything looked to be in great shape. They also had the best prices of several vendors that I looked at. I would strongly recommend anyones next purchase to take a good look at THMOTORSPORTS as they definitely delivered on this purchase.

Great!

Thanks

Product shipped from Norfolk VA, which was very convenient to me in NC. Arrived in a few days from ordering.
