Present disclosure describes a shot peening flow control valve for regulating flow of ferromagnetic media. The shot peening flow control valve comprising a body enclosing a passage for transferring the ferromagnetic media from a first end of the passage to a second end of the passage and at least one core set arranged between the first end and the second end. The at least one core set comprises at least one magnetic unit, and the at least one magnetic unit is operable to provide a magnetic field at the passage. The at least one magnetic unit may project or provide the magnetic field at the passage in order to regulate, control, or stop the flow of ferromagnetic media. Thus, the shot peening flow control valve facilitates effective control of the ferromagnetic media during the shot peeing process.
