Lennox 14W93 Expansion Valve 323080-701 If the display shows persistentThe Lennox 14W93 Indoor Expansion Valve is a critical metering device designed for precision refrigerant control in residential and commercial evaporators. This HVAC TXV operates by modulating the flow of refrigerant based on the heat load, ensuring the evaporator coil maintains the correct superheat for peak thermal exchange. Engineered for R22 systems, the 14W93 (which is functionally identical to 14W9301) prevents liquid slugginga common cause of
