ABSTRACT OF THE DISCLOSURE A pressurized fluid jetting device for use is a color sorting apparatus for sorting granular materials according to their colors by the blowing action of a pressurized fluid from the pressurized fluid jetting device. The device has a main body portion having a cylindrical member, a cap member detachably secured to the outlet end of the main body portion with a valve seat member and a pressure receiving plate fixed therebetween, and a valve plate movable between the valve seat member and the pressure receiving plate. The cylindrical member has an internal cavity defining a fluid passage connected to a source of a compressed fluid such as compressed air and a solenoid means adapted to be selectively energized in accordance with the state of detection of grains of different colors. Usually the valve plate is pressed onto the valve seat member to shut off the flow of the fluid but, as the solenoid means is energized, the valve plate is strongly attracted to strike the pressure receiving plate to cause a rapid wear of the latter as a result of a frequent repetitional operation. The pressure receiving plate can be renewed easily because it is formed as a body separate from the cylindrical member constituting the main body of the device.
