Silicon carbide ball valve

  • Finished product characteristics

    ● High abrasion resistance ● High corrosion resistance ● High oxidation resistance ● Strength does not change under high temperature environment ● Good self-lubrication ● Anti-erosion

  • Product characteristics

    Using high purity silicon carbide powder, isostatic molding, high hardness, high strength, high accuracy of the ball center, and the seat after grinding, the use of ceramic self-lubrication, with good sealing performance. The ball valve has two kinds of V-type and O-type spool, which can adjust the flow rate with high precision. At the same time, the use of reinforced spool also minimizes the wear of the valve flow path.

  • Precision machining

    1. High purity silicon carbide powder

    2. Open mold processing: dry pressing, CIM injection molding, isostatic pressing.

    3. Appearance processing: surface grinding, outer diameter/inner diameter grinding, fine engraving machining, grinding, polishing grinding.

  • Application field

    ● New energy ● Crude oil ● Chemical ● Steel ● Papermaking ● Chemical ● Pneumatic transport ● Fertilizer ● Mechanical wear ● Aerospace ● Military and so on.
