Detailed Product Description

Applications: electronic expansion valve is used for home air conditioners, mainly
installed in the converter air conditioning system, to regulate the refrigerant
flow automatically. Hence, the air conditioning system will keep working with
the best capacity, quick cooling, accurate temperature controlling and power saving.
The electric expansion valve can also be used for other kind of flow controlling
due to automatic controlling performance of the refrigerant flow under cooling
and heating conditions
