Trane VAL7574 Thermal Expansion Valve 3/8 X 5/8 2.5Ton 36" Capillary

The Trane VAL7574 Thermal Expansion Valve. A refrigeration valve that automatically controls the flow of the refrigerant in residential climate control applications. Compared with simple on/off valves, the TXV is one of the most essentialcomponents in the system and its performance directly affects the efficiency and safety of the system. This is because when the VAL7574 is connected to a thermal sensor bulb using a long, thin capillary tube 36” the TXV regulates the refrigerant flow into the evaporator coil based on the temperature of the bulb. The valve itself has sweat connections for brazing during installation and is made of stainless steel for R-22 refrigerant.
