Carrier EA660003 Thermostatic Expansion Valve (TXV) 5-Ton

The Carrier EA660003 is a Thermostatic Expansion Valve that was designed for use in Carrier HVAC systems of 5-ton and R-410A refrigerant it is an essential expansion device that controls the amount of refrigerant that is allowed into the evaporator coil. To measure the temperature of the refrigerant leaving the evaporator, there is a certain type of sensor with the bi-metal element. Depending on this temperature, the TXV changes a valve to allow only the right amount of refrigerant into the evaporator. This control of refrigerant flow enhances system efficiency and performance by allowing the evaporator to collect as much heat as possible without allowing liquid refrigerant to enter the dangerous compressor.
