ABSTRACT:
A ball valve apparatus for a refrigeration system is described. The ball valve apparatus comprises a ball valve for controlling flow of refrigerant and a moisture indicator for showing a moisture content of the refrigerant, and the moisture indicator and the ball valve are formed as one body. Since a moisture indicator and a ball valve are formed as one body, the installation cost and the size of a refrigeration system can be reduced.
