Carrier EA36YD129 Thermal Expansion Valve (Txv) 2Ton

The Carrier EA36YD129 is a 2-ton thermal expansion valve for Carrier air conditioners only. This is a small component which fits in the finger and plays a significant role of controlling the refrigerant flow within the system which leads to enhanced cooling ability. It is known as a TXV and works as a pressure-controlled by means of a bi-metal spring element. When cold air is being made the TXV checks the temperature and pressure of the refrigerant that is the evaporator coil. The bimetallic spring is sensitive to changes in temperature. When the pressure is high this indicates that the coolant is low and the spring pushes the valve and allows more cool liquid refrigerant into the coil.
