Ball valve, particularly for air conditioning and/or refrigeration systems

A ball valve, particularly for air conditioning and/or refrigeration systems, comprising:

• a valve body which has a substantially axially symmetrical geometry with a circular base with respect to a longitudinal axis and defines inside the valve body a first chamber and a second chamber which communicate with each other through a central hole;
• said first chamber being of a type that is open at an end portion thereof for insertion therein of a valve assembly and an actuation assembly, respectively;
• said valve body comprising a hollow connecting portion, located and extending along said longitudinal axis on an opposite side with respect to said first chamber and configured to be connected to a first connecting pipe of a refrigeration system or the like;
• said valve assembly being accommodated in said first chamber and having an actuation axis which is substantially perpendicular to said longitudinal axis;
• said actuation assembly being accommodated in said second chamber along said actuation axis;
• a sleeve which is removably associated with said valve body at said end portion by virtue of screw means so as to close said first chamber;
• said sleeve being configured to be connected to a second connecting pipe of a refrigeration system or the like.
