Structural characteristics of forged steel ceramic ball valve   1. The thickness of valve shell exceeds the requirements of standard data, with three-stage structure design and solid shape. Beautiful appearance  2. The sealing surface is precisely ground to ensure zero leakage  3. All the materials in contact with the medium are structural ceramics with high wear resistance. Oxidation resistance and corrosion resistance   Application Specification for forged steel ceramic ball valve Design and manufacture ASME B16.34 Connection end size Structural length ASME B16.10 Flange size ASME B16.5 Inspection and test API 598 All external surfaces of valve body shall be machined Main parts and materials of forged steel ceramic ball valve Serial number name Material Science 1 End valve cover F304 2 Mesosoma F304 3 Middle sleeve alumina ceramic 4 O-ring Fluororubber 5 Flange sleeve alumina ceramic 6 The Ball alumina ceramic 7 O-ring Fluororubber 8 Disc spring 50 CrVA 9 Washer 304 10 Stem Z276 11 filler PTFE 12 Hexagon nut 8 13 Bolt B8 14 Packing gland 304 15 Limiting plate 304 16 Handle 304 17 Fixing screw B8 18 valve seat alumina ceramic Main connecting dimensions of forged steel ceramic ball valve NPS L d D D1 D2 C F H n-M 1/2" 108 10 89 60.5 35 11.2 1.6 80 4-M14 3/4" 117 15 99 70 43 12.7 1.6 95 4-M14 1" 127 20 108 79.5 51 14.2 1.6 110 4-M14 1-1/2" 165 32 127 98.5 73 15.7 1.6 142 4-M14 2" 178 40 152.5 120.5 92 19 1.6 185 4-M16 2-1/2" 190 50 178 140 105 19 1.6 210 4-M16 3" 203 65 190 152.5 127 24 1.6 230 4-M16 4" 229 80 229 190.5 157 24 1.6 265 8-M16 5" 245 100 254 216 186 24 1.6 305 8-M20 6" 267 125 279 241.5 216 25.4 1.6 340 8-M20 8" 292 150 340 298.5 270 28.4 1.6 420 8-M20
