    Description

    Thin Type Single-plate Wafer Check Valve

    This 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 of Thin Type Single-plate Wafer Check Valves:
    One Piece Forged Steel Body
    Short Face-to-face (Thin Type)
    Reduced Bore, Swing Plate
    Disc Spring Available
    O-ring on Body Available

    Applicable Standards of Thin Type Single-plate Wafer Check Valves:
    a) Design&Manufacture:API 6D, API 594
    b) Face to Face: API 6D, ASME B16.10, EN 558
    c) Connection End: ASME B16.5, EN 1092, JIS B2220
    d) Test and Inspection: API 6D, EN 12266, API 598

    Sizes: 2" - 36" or DN50 - DN900
    Pressure Rating: Class150 - Class600 or PN16 - PN100
    Material of Valve Body: WCB, LCB, WC6, WC9, C12, C5, CF8, CF3, CF3M, CF8M, etc.
