Valve for spraying coating material, and an atomizer including such a valve

A valve comprising:

• a body;
• at least one first duct for channeling a flow of a fluid;
• at least one second duct for channeling another flow of a fluid;
• a first needle mounted to move in translation, in a first direction, between an open position and a closed position for opening and closing the at least one first duct, the body forming a first seat for the first needle;
• and
• a second needle mounted to move in translation, in a second direction, between an open position and a closed position for opening and closing the at least one second duct;
• where the first direction and the second direction are parallel or coincide, the first needle defines a recess for receiving the second needle, the first needle forms a second seat for the second needle and the body defines the at least one first duct, and the second needle has an internal cavity forming a portion of the at least one second duct, the valve being characterized in that:
• the body has an opening common to the at least one first duct and to the at least one second duct and
• the first needle and the second needle come flush with said opening.
