This simple electronic expansion valve is mainly applied in household frequency conversion AC system to control of refrigerant

This simple type electronic expansion valve is mainly applied in household frequency conversion AC system to control of refrigerant flow rate automatically,thus make air-conditioning system to work in the best situation and to realize fast freezing,temperature controlling and power saving.

Explanation:

1)      Please confirm about the matching characteristic of the system;

2)      Please install strainers(more than 100-mesh screen) in front of valve in the air-conditoner electronic expansion valve.

3)      Please keep the temperature of valve body below 1200C when manufacturer assembles and brazes the tube.

4)      If falling to the ground or collision.please use it after our retext
