Product Details
Metal to metal ball and seats kit includes one ball and two seats for metal seated ball valve. They are already lapped together and tested with alcohol or kerosene to guarantee as “Zero leakage” and/or “bubble tight seal”. 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.
