Description
The Carrier 340620-714 TXV Kit is an OEM-grade thermostatic expansion valve (TXV) replacement kit engineered for use in compatible Carrier refrigeration and air conditioning systems. Designed to maintain precise refrigerant metering, this TXV kit helps optimize system efficiency, protect the compressor, and ensure consistent cooling performance across a wide range of operating conditions.
Why Replace Your TXV?
A properly functioning thermostatic expansion valve is critical to the efficiency and longevity of any refrigerant-based HVAC system. A failing or worn TXV can result in poor cooling performance, compressor damage, high energy consumption, and refrigerant flooding or starving of the evaporator coil. Replacing it with the Carrier 340620-714 TXV Kit restores proper refrigerant flow and system balance.
