The Carrier EA36UZ067 Thermal Expansion Valve (TXV) is an essential part of Carrier HVAC systems that use R-410A refrigerant. It is a small box-like device with dimensions of 5 x 3.25 x 3.5 inches, and this is essentially essentialin controlling the refrigerant flow in the system. The TXV has a bi-metallic component that changes its dimensions with changes in temperature. This expansion and contraction control the refrigerant flow to the evaporator coil to make sure it cools properly for the greatest efficiency of the entire working process.
