The valve meters that flow so the amount entering the coil stays controlled rather than flooding the evaporator. As refrigerant passes through this point, the system shifts from the higher-pressure side toward the lower-pressure cooling stage. That change is what allows the evaporator to absorb heat from the air moving across it. Stable metering at this location is essential to how the cooling cycle operates.
