    Wafer-Check Valve


     Hebei Metals supplies Wafer Check Valves.

     Our wafer check valve series cover a wide range of material specification

     includingcast iron, ductile iron, carbon steel, stainless steel and aluminium  












    Specification of Wafer Check Valves:

    1. Brief Introduction:

        The wafer check valve, also known as "Dual Plate Check Valve", have two spring loaded half-moon shaped discs 

        that rotate about their shaft. The disc plates are kept shut by a torsion spring. When fluid flows in a forward direction,

        the pressure of the fluid causes the disc plates to swing open, allowing medium flow through the passage. The 

        check valve is closed by the spring as soon as the flow ceases, before any reversal of flow can occur.

    2. Material Specification:

        Body & Disc: WCB, LCB, CF8, CF3, CF8M, CF3M, Aluminium Bronze

        Pin: F6a, F22, F304(L), F316(L), F321

        Spring: AISI 9260, 6150; SS304(L), SS316(L), SS321

    3. Size Range & Pressure Ratings:

        2" ~ 24" (DN50 ~ DN600);  150LB ~ 900LB

    4. Standards:

        API 6D, API 594, ASME B16.34, ASME B16.5, ASME B16.25, ASME B16.10, MSS SP25
