Brief introduction

1, RF type expansion valve is a traditional thermal expansion valve.

2, It is used for regulating the liquid refrigerant's supply qantity in evaporator.

3, It is suitable for the supply of the refrigerant in dry-type evaporator.

4, It can control automatically by the superheat degree of refrigerant.

5, It has two connecting format, including lamp base and welded junction.

6, The capillry's length of RF type expansion valve is a standard of 1.5 meters.
