The surface material can be tungsten carbide, chrome carbide or stellite coating. These hard and resistant overlays can protect the material from corrosion medium. Reliable sealing for metal seated ball valve in critical applications makes the ball valve long life cycle, high wear resistance and high erosion resistance.
