Lennox 12J35 Expansion Valve 30067439-890 where maintaining specific timing forThe Lennox 12J35 Expansion Valve is a precision engineered NXT thermostatic expansion valve specifically calibrated for HVAC systems in the 3 to 3. 5 ton capacity range. Designed for indoor evaporator coils, this TXV utilizes a responsive sensing bulb to modulate refrigerant flow in real time, maintaining precise static superheat across varying thermal loads. By preventing liquid slugging and evaporator starvation, the 12J35 ensures the compressor
