What is Expansion Valve Use For?
Expansion Valves are used to expand liquid refrigerant from a higher pressure and a higher temperature to a lower pressure and a lower temperature.
As a controller for superheat, Expansion Valves control the refrigerant mass flow depending on evaporating pressure and temperature at the outlet of the evaporator.
They adjust the quantity of the injected refrigerant exactly and guarantee an economic function by optimal use of the evaporator surface.

Why need to choose correct expansion valve?
Thermal expansion valve matching plays an important role on performance of entire system, and suitable expansion valve will maximize use it and make evaporator perfectly match with thermal loads.
How to choose correct suitable Expansion Valve?
You can choose according to refrigerant of your refrigeration system, the range of evaporation temperature and evaporator superheat load size.
Method and steps:
1: Confirm refrigerant type
2: Confirm the range of evaporation temperature
3: Cooling capacity.
4: Pressure difference between the import and export of thermal expansion valve.
5: Balance way of internal or external pressure.
6: Connector size
What will happen if expansion valve fails to match system?
If don’t match, it will make refrigerant system flow uneven, also lead to uneven of cooling capacity of thermal expansion valve.
When refrigerant amount is too small, lead to make evaporator liquid supply shortage, generating excessive heat, and adversely affect system performance. When refrigeration amount is excessive, causing the shock, the intermittent nature of evaporator liquid supply excess, resulting in sharp fluctuations, sometimes maybe the compressor suction pressure liquid refrigerant enter compressor.
