PURPOSE: A high-pressure drop control valve with a three-dimensional flow path is provided to drop pressure and to prevent cavitation and a flashing phenomenon by increasing energy loss while fluid moves. CONSTITUTION: A high-pressure drop control valve comprises a disc-laminated body in which multiple discs(210-290) are laminated. Upper inflow passages(221,231,241) and upper discharge passages(225,235,245) are formed along the circumference of discs(220,230,240). Downward connection passages are formed in the ends of the upper inflow passages. Upward connection passages are formed in the ends of the upper discharge passages. The downward connection passages and the upward connection passages are communicated to each other so that fluid can gradually flow upward and downward while rotating along the circumference of the discs. Lower discharge passage(271,281,291) and lower inflow passages(275,285,295) are formed along the circumference of the discs.
