Ceramic ball by ball and seat are made of wear resistant ceramic manufacturing, parts are made of ceramic bushing a high abrasion resistance and corrosion resistance of the ball valve body contact with the media. Structural ceramic material is a high-tech ceramic material, its chemical properties is extremely stable, the deformation is small, has a very high hardness (Rockwell hardness HRC90 second only to diamond) and a great deal of strength and toughness. ; Ceramic valve has a very high wear resistance, corrosion resistance, high temperature resistance, erosion resistance, and good thermal insulation properties, thermal expansion coefficient, fire protection and antistatic. The ceramic itself has a self-lubricating, so that the ceramic ball valve torque is small, sealed tight. Applicable to strong acids, alkali, high temperature, high hardness particles, gas-solid two-phase, solid-liquid two-phase gas solid-liquid equal to harsh working conditions, with metal valves can not match advantage. Widely used in power plant desulfurization, chemical plants, paper mills, steel mills, petroleum, metallurgy and other poor working conditions in the industry; the ceramic ball main performance parameters: product name: ceramic ball; product Model: Q41TC Q341TC; DN: DN15- DN300 (1/2 "-12"); said pressure: PN1.6MPa ~ PN6.4MPa (CLASS150Lb ~ CLASS600Lb); access: flange; dynamic way: manual, gears; material: carbon steel, stainless steel; using the media : acid, alkali, high temperature, high hardness particles, gas-solid two-phase, solid-liquid two-phase gas solid-liquid equal to the medium; Operating temperature: -29 to 600 ° C;
