Lennox 56J19 Thermal Expansion Valve(TXV) Kit R22 1.5-3 Ton 18"

The Lennox 56J19 Thermal Expansion Valve (TXV) Kit is an original replacement part used in indoor HVAC systems with capacities of 1.5 to 3 tons. It controls the flow of refrigerant by using the temperature sensor of the air evaporator coil. This has the effect of creating fine-grain control over the system’s performance and enhancements. The TXV has no bleed port and is easy to install and has Chatleff connections for integration with other systems. An external equalizer also guarantees precise control of the refrigerant to avoid overfeeding or even flooding the compressor. The included 18-inch capillary tube is convenient for a wide range of evaporator coil designs.
