The ProTech® thermostatic expansion valve (TXV or TEV) is an essential refrigeration and aircon TX valve that adjusts the refrigerant flow into the evaporator coil based on temperature sensing. The AC unit expansion valve plays a critical role in the refrigeration cycle by controlling the volume of liquid refrigerant entering the evaporator to ensure the system operates at its best. Additionally, the TXV valve features a balanced port design with an integrated check valve assembly, specifically engineered for residential and small commercial heat pumps that necessitate a check valve.
