Carrier EA36YD199 Thermal Expansion Valve

The Carrier EA36YD199 thermostatic expansion valve (TXV) is used with HVAC systems using R-410A refrigerant. In a refrigeration system this valve is crucial control device that regulates the flow of refrigerant. It's sensitive temperature of the refrigerant leaving the evaporator coil. The TXV will open when the temperature gets too high, so more cool refrigerant can enter the coil increasing cooling efficiency. However, if the temperature goes low enough, the TXV will restrict the flow of refrigerant, which results in no formation of ice on the coil.
