Product Name: Thin Type Single-Plate Wafer Check Valve Model NO.: H77H Application: Industrial Usage, Water Industrial Usage, Household Usage Standard: ANSI Flow Direction: Unidirection Sealing Form: Gland Packings Globe Valve Pressure: Ordinary Temperature Structure: Swing Connection Form: Wafer Material: Cast Steel Temperature: Low Temperature Media: Oil Color: Custom Trademark: Fly Transport Package: Plywooden Case Specification: 1" - 48" Origin: Zhejiang Province, China HS Code: 8481804090 Product Description Thin TypeSingle-plate Wafer Check ValveThis thin type of single-plate wafer check valves are swing type, that performs the same with swing check valve with much less cost. The disadvantage of this single-plate wafer check valves is, the inside diameters of the valves can only meet 60-80% of Norminal Pipe Size(NPS), which limits the flow coefficient.Features ofThin TypeSingle-plate Wafer Check Valves:One Piece Forged Steel BodyShort Face-to-face (Thin Type)Reduced Bore, Swing PlateDisc Spring AvailableO-ring on Body AvailableApplicable Standards ofThin TypeSingle-plate Wafer Check Valves:a) Design&Manufacture:API 6D, API 594b) Face to Face: API 6D, ASME B16.10, EN 558c) Connection End: ASME B16.5, EN 1092, JIS B2220d) Test and Inspection: API 6D, EN 12266, API 598Sizes: 2" - 36" or DN50 - DN900Pressure Rating: Class150 - Class600 or PN16 - PN100Material of Valve Body: WCB, LCB, WC6, WC9, C12, C5, CF8, CF3, CF3M, CF8M, etc.arts No.Parts NameMaterialWCBCF8CF8M1BodyA216 WCBA351 CF8A351 CF8M2DiscA216 WCB / A351 CF8 / A351 CF8M3Body SealNBR / EPDM / VITON / PTFE4SeatNBR / EPDM / VITON / PTFE / metaL / A.S.
