Trane BAYATXV4248B Field Mounted Thermal Expansion Valve (TXV)

The Trane BAYATXV4248B is a field-mounted thermal expansion valve this simple replacement component is intended for Trane HVAC systems that use R22 refrigerant with capacities from 3.5 to 4 tons. Increasing cooling efficiency and protecting your compressor requires a TXV. A smart valve that controls refrigerant flow into the evaporator coil. The Trane has a thermal actuator that responds to the temperature of the evaporator coil. The TXV precisely measures the refrigerant according to system requirements, avoiding overfeeding, which reduces efficiency and can cause coil freeze-up, and underfeeding, which reduces cooling capacity.
