Nor-Lake 096422 Expansion Valve EFSE-1/4-ZP

The Nor-Lake 096422 Expansion Valve EFSE-1/4-ZP is a metering module fitted in the liquid line to manage refrigerant entry into the evaporator circuit. It opens and closes based on the pressure and temperature balance between inlet charge conditions and outlet superheat, allowing a controlled amount of refrigerant to pass through the internal orifice. The body connects to the inlet and outlet tubing, where phase change begins regulating distribution, into the cooling coil. It ensures a consistent reagent feed into the evaporator passages so heat exchange remains stable across repeated cooling cycles inside the refrigeration system.
