Description
The Lennox 12J38 Indoor Thermal Expansion Valve regulates refrigerant flow into the evaporator by controlling superheat according to system demand. This is used in air conditioning and refrigeration equipment within HVAC systems to ensure accurate metering across the coil. Rated for 2.5 tons capacity, it modulates flow based on temperature sensing at the evaporator outlet. The valve maintains pressure balance, supports efficient heat transfer and reduces compressor strain by preventing improper refrigerant return while ensuring steady evaporation under changing load conditions.
