‎Thermostatic expansion valves regulate the flow of liquid refrigerant in evaporators. The superheating of the refrigerant fluid controls liquid injection. Thermostatic expansion valves act as throttle between the high and lowpressure sides of refrigeration systems and ensure that the refrigerant flow rate into the evaporator matches the rate of evaporation of liquid refrigerant in the evaporator.
