Mit Flansch (RF) Verbindung Absperrschieber

FeatureFlow resistance is small. The inner medium channels of valve body is direct, medium is flowing in line. .On-off is laborsaving, compare with globe valve, no matter when is open or close, the working of the wedge is vertical with the medium flows. Medium can flow each side, and easy to setting.When full open, the erosion of the sealing surface with working medium lower than the globe valve. The water hammer is not easy to come, because the close time is long.Applicable scopeWater supplyOilarchitectureMedicineChemistryFoodstuffPower stationMetallurgyshippingenergy sourcesMain partsPart namevalve bodyBonnetDiscStemMaterial and StandardASTM A216 WCB ASTM A216 WCB ASTM A276 304 GB/T 1220 2Cr13 Nitrogenization ASTM A352 LCB ASTM A352 LCB GB/T 1220 3Cr13 GB/T 1220 2Cr13 Nitrogenization ASTM A351 CF8MASTM A351 304GB/T 699 25#/ASTM A351 304 ASTM A494Hastelloy C-22/C-276 / / ASTM A494Hastelloy C-22/C-276 ASTM A995 CD4MCu / / ASTM A995 CD4MCu/// Performance specificationNominal pressure (MPa)Class150Class300Class600Test pressureMPaShell test3.07.516.5Upper sealing testhigh pressure sealing test2.25.512.1Low pressure air tight test0.60.60.6Maximal working temperature(°C)≤230≤230≤230Applicable medium: water,steam,oil etc. DriveBevel wheelElectricComment: According to the client’s requirements, we can set the appointed drive.
