Principle of the cast steel floating ball valve: This kind of floating ball valve has a ball supported by two valve seats. Under the medium pressure effect,a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.The floating ball valve is mainly divided into such two structures as the single-body type and double-body type.Valve FeaturesSplit body design with flanged ends for fast installation, in-line maintenance and rebuildingSolid ball construction provides structural integrity and minimizes flow turbulenceMounting pad complied with ISO 5211 for ease and interchangeability of actuationBottom-loaded blow-out proof stemInvestment cast body & cap on sizes 1/2"to 4"Sand cast body & cap on sizes 5" to 10"Body joint is designed to prevent excessive compression of valve internals, resulting in a consistent and low operating torqueBasic design complied with ASME/ANSI B 16.34Flanged ends complied with ASME/ANSI B 16.5Face-to-face dimensions complied with ASME/ANSI B16.10Tested according to ANSI B 16.34 & API 598Design FeaturesThe floating ball valve are designed in accordance with ISO17292ã??API 608ã??BS 5351ã??GB/T 12237;Simple structure with good tightness and small torque;Have reduce bore type and full bore type with the minimum flow resistance (zero actually);Low emission packing;Fire safe, anti-static and anti-blowout stem design;Optional locking deviceOptional ISO 5211 top flangeProduct RangeBody material: carbon steel, stainless steel, alloy steelNominal diameter:1/2"ï½?10"ï¼?DN15~DN250ï¼?End Connection: RF, BW, THRPressure range: Class150 â?? 300ï¼?PN16~PN40ï¼?Operation: wrench, worm gear, electric, etcBrand3DValve TypeCast Steel Floating Ball ValveValve MaterialCast steel, stainless steel, special  alloy, etcValve Test100% quantity tested before deliveryValve Guarantee18 months from the date of dispatch ex works,  or 12 months from date of commodity installation.Valve PaintingCustomer requestValve PackageWooden caseMOQNo requirementValve CertificateAPI 6D/CE/ISO9001/ISO14001Delivery DetailShipped in 4 or 6 weeks after paymentPortHoustonPayment TermsL/C,D/A,D/P,T/TCertificate OfferedPacking List,Commercial  Invoice,Test Reports and Material Certificates,Certificate  of quality and quantity, Sellerâ??s Certificate of Guarantee
