Green SiC powder 25um-28um for polishing floating ball of ball valve
Usually, a layer of hard alloy material is coated on the valve body and floating ball by plasma thermal spraying technology to improve its wear resistance. It is necessary to make surface treatment on the floating ball to ensure its surface smoothness and flatness. Green SiC powder 25-28um is hard and sharp enough for grinding hard alloy coated floating ball of ball valve.
