PURPOSE: A three-way valve system using a servo motor is provided to accurately control pressure and the required amount of water and to freely control the height of a fountain. CONSTITUTION: A three-way valve system using a servo motor comprises an upper cover(11), a lower cover(12), and a servo motor(13). The upper and lower covers protect the servo motor. The shaft(15) of the servo motor is integrally assembled in a coupling(16) and is fixed to the bolt(17) of a three-way ball valve(18). When the shaft of the servo motor is rotated, the bolt connected to the coupling is rotated. The three-way ball valve, integrally formed in the servo motor, accurately operates the opening and closing of a three-way ball.
