ABSTRACT:
A valve device of an application device for applying fluid to a substrate comprises a valve body, a valve housing with inner chamber and valve seat, a supply fluid chamber, an electromagnetic valve actuating device with valve piston and an adjusting piston. The valve nozzle is detachably mounted on the nozzle side of the valve device. The valve device has a nozzle plate which closes the valve body at the bottom on the nozzle side, with mounting opening for the valve piston. The valve housing is designed in the form of a nozzle orifice which is a closure member that can be fitted on the mounting opening from below and removed. The valve nozzle forms part of the valve housing. The valve piston is exposed through the mounting opening of the nozzle plate for removal and fitting when the closure member is removed. The valve device is provided with at least one rectilinear fluid duct that connects the supply fluid chamber to the valve seat. The valve piston and part of the adjusting piston together form a wall of the straight fluid duct which, when the nozzle orifice closure member is removed, is exposed for cleaning through the mounting opening. An application device comprises the valve devices arranged in a row.
