It is the accumulator's internal ※2 O-ring material for gas charging valve, for connection port of SG vavle and Top Cap, and for built in SG valve is NBR.※3 When bladder compound is L.NBR, O-ring material for gas charging valve, for connection port of SG vavle and Top Cap, and for built in ※4 Regardless of the bladder compound, material of seal washer for SG valve is NBR.※5 Please refer to page 104 ⑪ accessories supplied with bladder for further information.＊ Use over a long period of time at the maximum allowable service temperature should be avoided since it accelerates bladder deterioration. ＊ Fluorine rubber has excellent chemical resistance. However, be aware that the rubber swells with ether, ester, ketones, or methyl alcohol, ＊ Note that use with petroleum based fluids may cause the extraction of unspecified substances from synthetic rubber (bladder and O-ring), ＊ A button is located at the bladder bottom for J series accumulators. The standard bladder designation for the J series is "B".②Bladder Compoundtemperature.SG valve is also L.NBR.Use at 80% of the maximum allowable service temperature (70% in the case of horizontal installation) or less is recommended.hardens with anhydrous ammonia or activated amines, and is eroded by strong alkalis.resulting in fluid discoloration.28SymbolAreaCountryU.S.A.TAIWANFranceJapanMarineJapanU.K.South KoreaNorwayChinaXSpecialSpecialOther Special InspectionSelect the item number code corresponding to the material suitable for "service fluid" and "service temperature".※1SymbolBladder CompoundStandard Nitrile RubberStandard Nitrile Rubber bladder with oil port valve molded inNitrile Rubber for high temperature useNitrile Rubber for low temperature useButyl RubberEthylene Propylene RubberChloroprene RubberEpichlorohydrin RubberFluorine RubberInspection·RegulationABSAmerican Bureau of ShippingCRChina Corporation Register of ShippingBureau VeritasBVMinistry of Land, Infrastructure, Transport and Tourism, JapanJGNKNippon Kaiji KyokaiLRLloyd's Register of ShippingKRKorean Register of ShippingDNVDNV ASCCSChina Classification SocietyNBRNBRH.NBRL.NBRIIREPDMPhosphate Ester Based FluidCRCHCFKMSuitable Service FluidTurbine Oil (jis K2213)Fatty Acid Ester FluidWater Glycol FluidW/o Emulsion FluidO/w Emulsion FluidBiodegradable FluidTap WaterSea WaterPhosphate Ester FluidBasic, WaterRemarksThe ship owner should specify the applicable ship class.
