The Lennox 12J20 is a genuine OEM thermostatic expansion valve (TXV) kit manufactured by Danfoss for Lennox residential and light commercial HVAC systems. Designed for use with R-410A refrigerant, this externally equalized, non-bleed valve precisely meters and regulates the flow of refrigerant into the indoor evaporator coil based on system load. This helps maximize efficiency, maintain stable temperatures, and protect the compressor from liquid slugging in 3.5 to 5-ton air conditioning and heat pump systems.
