VAL19629
Trane VAL19629 3-Ton Thermal Expansion Valve TXV is a critical component of HVAC systems that accurately regulates refrigerant. This 3-ton TXV, with a 3/8” inlet port and a 1/2” outlet port, works by measuring the temperature of the refrigerant leaving the evaporator and then regulating the amount of refrigerant to ensure the right amount of superheat. Such fine-tuning ensures optimum utilization of the system and hence conserves energy and lowers the overhead costs. The TXV has the positive impact on the increase of system reliability and the increase of equipment’s working life. Designed for use with air conditioners, heat pumps and chillers.
