Description
The Carrier EA36UZ939 Thermostatic Expansion Valve (TXV) is a metering component used to regulate the flow of refrigerant into the evaporator coil. It responds to temperature and pressure changes in the system to maintain controlled refrigerant entry and stable evaporation conditions. It is used in air conditioning and heat pump equipment where precise refrigerant distribution is required for consistent cooling performance. In HVAC systems it is fitted within the liquid line upstream of the evaporator section, supporting balanced coil operation, maintaining appropriate superheat levels, and ensuring steady thermal exchange across the refrigeration cycle.
