A Dart or Valve plug for opening, Closing or Modulation of Abrasive FLUID FLOW, such as Pulp or Mineral Tailings, whether for Systems working at Atmospheric Pressure or pressure, which prevents Turbulence and Vibration, which comprises a Stopper attached in the lot N superior to a STEM, all being enclosed by a Valve Body.In the Valve Body is connected with an inlet pipe and an outlet pipe, wherein the connection between the Outlet Pipe and the Valve Body Is A Seat, where the said Plug is in the shape of an inverted Pyramid of polygonal base and the seat has a Polygon Perimeter, which FITS with the Outer surface of the CAP.The Invention also relates to a Valve of dart to be used in Abrasive Fluids with large particle size, such as Stones, preventing the proper Modulation of the Fluid
