The Lennox 64W49 Cap Thermal Expansion Valve (TXV) (around 0.94 lbs) is a key control component designed for Lennox air conditioners with a 4-ton cooling capacity (verification for compatibility with other brands using similar TXVs is necessary). Made from durable materials, this valve plays a central role in optimizing system efficiency and cooling performance. The 64W49 TXV uses a long, thin capillary tube (30 Inches) to monitor the temperature within the evaporator coil. Based on this temperature, it precisely regulates the flow of refrigerant entering the coil through the 3/8-Inch diameter inlet. The outlet features a 1/2-Inch ODF (Outside Diameter Flare) connection for easy installation within compatible refrigerant lines. This ensures the coil receives the optimal amount of refrigerant to absorb heat efficiently, maximizing cooling output. By precisely controlling refrigerant flow, the TXV contributes to a more efficient cooling process, potentially reducing energy consumption.
