Product Details

                                                    Metal Seated Ball Valve



Brief introduction of high-temperature ball valve metal seat

The ball and seat of the metal hard-seal ball valve completely adopt the metal-to-metal sealing method. In order to ensure the reliable sealing of the valve at various temperatures and pressures, according to the different operating conditions and requirements of users, a variety of advanced balls and The hardening technology of the valve seat includes supersonic spraying, nickel-based spray welding, special surface hardening, cemented carbide spray welding, and the use of high-strength and high-hardness ceramic materials. The surface hardness of the ball and valve seat can generally reach HRC60 or higher, and the highest Above HRC74. The temperature resistance of the sealing surface material can reach 540℃, and the high can reach 980℃. The bonding strength of the material can reach more than 10000PSI, and the sealing surface material also has good abrasion resistance and impact resistance. The metal hard seal ball valve can be suitable for most of the harsh working conditions.
