Lennox 70M29 Expansion Valve Refrigerant as the voltage rating representsThe Lennox 70M29 Expansion Valve is a critical OEM replacement part engineered for precise refrigerant metering in residential and commercial cooling systems. This thermostatic expansion valve (TXV) is designed to regulate flow based on evaporator load, ensuring maximum heat exchange efficiency and preventing liquid slugging in the compressor. The 70M29 is technically identical to 70M2901 and serves as a direct replacement for legacy part numbers
