A portable spraying apparatus for discharging a fluid, in particular an agricultural formulation, having a container for holding the fluid, a pump, which is fluidically connected to the container, for conveying the fluid out of the container, a spray gun, which comprises a spray opening and an electrically actuatable application valve for opening and closing a passage to the spray opening, an application line, which establishes a fluidic connection between the pump and the spray gun, a pressure sensor, which is arranged in the application line, for detecting the fluid pressure in the application line, and an electrical control apparatus, which is coupled to the application valve and the pressure sensor in terms of data transmission and by way of which, in a manner dependent on the fluid pressure detected by means of the pressure sensor, an electrical control signal for opening the application valve for a specific predefined time interval and for closing the application valve after the time interval has elapsed is able to be generated such that a defined volume of the fluid is discharged via the spray opening, wherein the application valve is a shut-off valve having a shut-off body for closing a valve passage, and the application valve has a valve spring, which, for closing the valve passage, exerts a force on the shut-off body in the direction of a valve seat or which, for opening the valve passage, exerts a force on the shut-off body in the direction away from the valve seat, and wherein the application valve has a valve chamber, which is fluidically connected to the application line, wherein the shut-off body is arranged relative to the valve chamber and the valve seat such that a fluid pressure from a fluid situated in the valve chamber pushes the shut-off body onto the valve seat. a container for holding the fluid, a pump, which is fluidically connected to the container, for conveying the fluid out of the container, a spray gun, which comprises a spray opening and an electrically actuatable application valve for opening and closing a passage to the spray opening, an application line, which establishes a fluidic connection between the pump and the spray gun, a pressure sensor, which is arranged in the application line, for detecting the fluid pressure in the application line, and an electrical control apparatus, which is coupled to the application valve and the pressure sensor in terms of data transmission and by way of which, in a manner dependent on the fluid pressure detected by means of the pressure sensor, an electrical control signal for opening the application valve for a specific predefined time interval and for closing the application valve after the time interval has elapsed is able to be generated such that a defined volume of the fluid is discharged via the spray opening, wherein the application valve is a shut-off valve having a shut-off body for closing a valve passage, and the application valve has a valve spring, which, for closing the valve passage, exerts a force on the shut-off body in the direction of a valve seat or which, for opening the valve passage, exerts a force on the shut-off body in the direction away from the valve seat, and wherein the application valve has a valve chamber, which is fluidically connected to the application line, wherein the shut-off body is arranged relative to the valve chamber and the valve seat such that a fluid pressure from a fluid situated in the valve chamber pushes the shut-off body onto the valve seat.
