The invention relates to a regulating valve and discloses a balance cage type regulating valve. The balance cage type regulating valve comprises a valve body. A valve seat is arranged in the valve body. An upper sleeve is arranged above the valve seat. An opening is formed between the valve seat and the upper sleeve. A valve cage is arranged in the upper sleeve. The bottom end of the valve cage is abutted against the valve seat. One side of the opening is communicated with a two-section valve body inlet. The lower portion of the valve cage is communicated with a two-section valve body outlet. An inlet valve body is connected to one side of the two-section valve body inlet of the valve body. A one-section valve body inlet communicated with the two-section valve body outlet is formed in the inlet valve body. An outlet valve body is connected to one side of the two-section valve body outlet of the valve body. A one-section valve body outlet communicated with the two-section valve body outlet is formed in the outlet valve body. The one-section valve body inlet, the two-section valve body inlet, the one-section valve body outlet and the two-section valve body outlet are all in parallelogram shapes. The balance cage type regulating valve resistant to erosion is provided for solving the problem that a valve body of an existing regulating valve is eroded by media.
