Nor-Lake 154020 Expansion Valve EFSE-1/4-ZP

The Nor-Lake 154020 Expansion Valve EFSE-1/4-ZP is a flow-regulating component designed for compatible commercial refrigeration equipment. It is positioned between the liquid line and the evaporator where it meters the volume of refrigerant entering the evaporator coil according to system operating conditions. The valve respond to changes in evaporator outlet temperature through its sensing element adjusting refrigerant delivery to maintain proper evaporator performance. It operates with the compressor, condenser, liquid line and evaporator as part of the refrigeration circuit. This component operates within cooling system to regulate refrigerant flow and support consistent temperature control throughout the refrigeration cycle.
