A spray nozzle device, a spray boom and an operating method for a spray nozzle device is disclosed. The spray nozzle device comprises a single nozzle (100, 200) having a fluid inlet (20, 206), at least one fluid outlet (40, 120A, 120B, 120C, 120D, 122) and multiple valves (30, 32, 34, 104A, 104B) that couple the fluid inlet (20, 206) to the at least one fluid outlet (40, 120A, 120B, 120C, 120D, 122) based on an open or closed position of at least one of the multiple valves (30, 32, 34, 104A, 104B), electronic traces that receive modulated duration signals (3, 5, 7), wherein a first electronic trace contacts a first of the multiple valves (30, 32, 34, 104A, 104B) to control its open or closed position, and a second electronic trace contacts a second of the multiple valves (30, 32, 34, 104A, 104B) to control its open or closed position； and the first of the multiple valves (30, 32, 34, 104A, 104B) is configured to move to a first open position in a different phase relationship with respect to a second open position of the second of the multiple valves (30, 32, 34, 104A, 104B), wherein the first open position and second open position are based on a duration and a polarity of the modulated duration signals (3, 5, 7) on the first electronic trace and on the second electronic trace, respectively. Furthermore, a spray boom is equipped with such a spray nozzle device and a method is defined for operating the above mentioned spray nozzle device.
