Expansion Valve

Please contract us for more detail description according to your need

Refrigeration system expansion valve is an important component, generally installed in the storage liquid between the tube and the evaporator. Expansion valve so that the temperature high-pressure liquid refrigerant through the throttling a low-temperature low-pressure wet steam, and then refrigerant in the evaporator to achieve cooling effect to absorb heat, expansion valve by the evaporator superheat at the end of the change of flow control valves to prevent the appears evaporator area and knock the phenomenon of under-utilized

heat transfer efficiency is high;
