A valve comprising: a casing forming an enclosure inside which a fluid is intended to flow and having at least one inlet and at least one outlet of the fluid; a shutter configured as to cooperate with a seat integral with the casing to close the at least at least one inlet or the at least outlet of the fluid; and a device for controlling the position of the shutter relative to the seat, wherein the control device comprises at least an inductor and at least one armature magnetically coupled and configured that the inductor drives the at least one armature in rotation so as to selectively cause the shutter to move closer to or to move away from the seat, wherein the at least one armature is positioned inside the enclosure and is stationary relative to a screw carrying the shutter and having a thread, with the thread of the screw configured to cooperate with a nut integral with the casing, so as to transform a rotation of the at least one armature into a translation of the shutter, and wherein the screw is hollow to define an inner passage for the fluid, and the screw has a wall, the wall having an inner face defining the inner passage and an outer face opposite to the inner face, said outer face being provided with said thread, and the valve is configured for the fluid to primarily flow from the at least one inlet to a first opening in the screw through the inner passage to a second opening of the screw to the at least one outlet.
