Marketing InformationWithin refrigeration and air conditioning systems, the Thermostatic Expansion Valve (TXV) serves as a vital valve that adjusts refrigerant flow into the evaporator coil based on temperature sensing. This ProTech® expansion valve is instrumental in the refrigeration cycle, precisely regulating the quantity of liquid refrigerant entering the evaporator to optimize system performance. Additionally, the Type CBBI thermal expansion valve is engineered with a balanced port design and integrated check valve assembly, ideal for residential and small commercial heat pump systems that demand dependable check valve operation.
