PURPOSE: A nozzle for fountain system is provided to produce various water shapes at low cost by controlling opening and closing time of the nozzle for fountain to less than 0.5 second as maintaining superior durability. CONSTITUTION: In constructing a fountain system nozzle capable of producing various water shapes by selectively opening and closing water pumped by a single pump from a plurality of nozzle bodies, the nozzle for fountain system is characterized in that water spraying nozzle body is integrally connected to control valve(5) by connecting socket which is formed at the lower part of the nozzle body, and in which vane is installed in the fountain system nozzle, the control valve(5) impresses an electrical signal to valve hole(7) on the body(6) through which fluid passes so that diaphragm assembly(8) is opened and closed, core assembly(9) is installed in the upper part of the control valve(5), core assembly(11) is inserted into the core assembly(9) so that the core assembly(11) is fixed to the core assembly(9) by washer(10), shaft ascending and descending hole(12) is formed in the core assembly(11) so that shaft(14) insertingly assembled into holder assembly(13) is connected to the lower part of the core assembly(11), the holder assembly(13) is elastically supported upward by return spring(15) so that the holder assembly(13) is positioned to the upper side when an electrical signal is not impressed to the shaft(14), and the return spring(15) and holder assembly(13) are rested on bonnet(17) fixed to the upper part of the body by bolts(16).
