1. The role and classification of expansion valves<br></br> Expansion valve is an important part of refrigeration system, generally installed between liquid storage cylinder and evaporator. The expansion valve causes the medium temperature and high pressure liquid refrigerant to become low temperature and low pressure wet vapor through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect.
