Description
The Lennox 72L34 is a 3-ton Thermal Expansion Valve (TXV) suitable for refrigeration systems Usesing R-22 or R407C refrigerants. Measuring 3.8 Inches long by 4.2 Inches wide by 3.5 Inches tall, this critical component helps. The key control factor is to prevent the exact quantity of refrigerant from entering the evaporator coil; thus, ensuring refrigeration. This precise control helps eliminate overfeeding of the refrigerant which in turn reduces the efficiency of the system and causes system failure. This one is used for flow rate applications to get the proper flow rate of the refrigerant depending on the conditions of the system.
