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

The Nor-Lake 154020 Expansion Valve EFSE-1/4-ZP is a cooling control part for commercial refrigeration systems. It controls the amount of refrigerant fed to the evaporator depending on the system condition. It is placed in the refrigerant circuit between the high-pressure side and the evaporator and it lower the pressure of the refrigerant before it reaches the evaporator coil. Its controlled flow supports the evaporator to perform its heat transfer process when cooling. It is used in the refrigeration system to control the flow of refrigerant to the evaporator and to assist in maintaining the operating conditions necessary for the proper operation of the refrigeration system.
