A tap head device comprising a pipe body with a first canal where the fluid passes through, wherein the pipe body enables the fluid flow to exit of the tap head device vertically downwards when in closed position, and a head with a union nut with a thread inside the union nut that enables the tap head device to be mounted on a tap system characterized by a junctional body connecting the union nut to the pipe body , wherein the junctional body and the connected pipe body comprise a lateral passage allowing for a fluid exit and a central screw hole , a rotating main body encompassing the pipe body and being rotatable around the pipe body , the pipe body and the rotating main body are kept together by a screw inserted in the screw hole and preventing the rotating main body from falling apart from the pipe body , while at the same time enabling the rotating main body to rotate around the pipe body , a second canal and a third canal of the rotating main body that enable to deviate the fluid flow laterally and upwards in an open position disabling a vertical fluid exit, wherein the rotation of the rotating main body moves the tap head device from the closed position that enables a vertical fluid exit and that closes a connecting aperture of the second canal hermetically, to the open position that enables to deviate the fluid flow laterally and upwards and that closes a forth canal disabling the vertical fluid exit; a trench milled in a base part of the rotating main body , said forth canal being part of the trench thereby providing for a smooth transition of the fluids flow between the closed and open position, and the aperture being situated vis-à-vis or at least offset to the trench , wherein for the open position, the main body is rotatable in such a way that the aperture communicates with the first canal inside the pipe body . a junctional body connecting the union nut to the pipe body , wherein the junctional body and the connected pipe body comprise a lateral passage allowing for a fluid exit and a central screw hole , a rotating main body encompassing the pipe body and being rotatable around the pipe body , the pipe body and the rotating main body are kept together by a screw inserted in the screw hole and preventing the rotating main body from falling apart from the pipe body , while at the same time enabling the rotating main body to rotate around the pipe body , a second canal and a third canal of the rotating main body that enable to deviate the fluid flow laterally and upwards in an open position disabling a vertical fluid exit, wherein the rotation of the rotating main body moves the tap head device from the closed position that enables a vertical fluid exit and that closes a connecting aperture of the second canal hermetically, to the open position that enables to deviate the fluid flow laterally and upwards and that closes a forth canal disabling the vertical fluid exit; a trench milled in a base part of the rotating main body , said forth canal being part of the trench thereby providing for a smooth transition of the fluids flow between the closed and open position, and the aperture being situated vis-à-vis or at least offset to the trench , wherein for the open position, the main body is rotatable in such a way that the aperture communicates with the first canal inside the pipe body . <EOS>
