The ProTech® Thermostatic Expansion Valve (TXV) serves as a pivotal refrigeration and air conditioning valve that regulates refrigerant flow into the evaporator coil through temperature sensing. These expansion valves are critical in the refrigeration cycle, controlling the amount of liquid refrigerant entering the evaporator to maintain peak system efficiency. Furthermore, the Type CBBI ac unit expansion valve is equipped with a balanced port design and integrated check valve assembly, specifically designed for residential and small commercial heat pump systems needing reliable check valve functionality.
