This utility model discloses a multi-stage pressure-reducing regulating valve for cavitation prevention, comprising a valve body. The valve body is characterized by a valve cover mounted on its top, an outlet pipe and an inlet pipe respectively located on opposite sides of the valve body, a valve seat mounted inside the valve body, a valve stem slidably fitted inside the valve body, a valve core corresponding to the valve seat mounted at the bottom end of the valve stem, a pneumatic actuator mounted on the top of the valve cover, and one end of the valve stem passing through the top of the valve body slidably fitted inside the valve cover and cooperating with the pneumatic actuator. The valve body contains a pressure-reducing inner cylinder and a pressure-reducing outer cylinder, with the outer wall of the inner cylinder and the inner wall of the outer cylinder in contact and in both sliding and rotating fit. This utility model, through the pressure-reducing inner and outer cylinders, enables the pressure-reducing inner and outer cylinders to reduce the pressure of the medium flowing within the valve body. This allows the medium to pass through multiple first and second through holes, and the first and second connecting grooves reduce the impact force of the medium, facilitating pressure reduction within the valve body and reducing cavitation.
