Carrier 332368-771 Thermal Expansion Valve (Txv) Kit

The Carrier 332368-771 Thermal Expansion Valve (TXV) Kit is approximately one of the most essential spare parts for particular Carrier air conditioners. This bi-metal TXV kit controls the flow of refrigerant which leads to proper cooling capacity. It contains a spring comprised of two different kinds of metal with different thermal coefficients. When cold air is produced, the TXV measures the pressure and temperature of the refrigerant that is leaving the evaporator coil. If the pressure increases too much, meaning that there is no coolant, the spring increases in size because of the heat.
