Nor-Lake 100556 Thermo Expansion Valve EFSE-1-C

The Nor-Lake 100556 Thermo Expansion Valve EFSE-1-C is a refrigeration control part for controlling the flow of cooling in a commercial system. It works based on a thermocouple sensing the amount of refrigerant flow to the evaporator as a operates of the temperature and pressure conditions, thereby ensuring stable cooling performance and correct evaporator superheat. It is placed in the liquid line in front of the evaporator coil, which it monitors for changes in system load to ensure efficient heat exchange and to prevent flooding or starvation of the coil. It is used in a variety of applications, including walk-in coolers, freezers, and commercial appliance units.
