    Full SPECIFICATION of Forged Steel Gate Valves:

    1. Brief Definition:

        Forged steel gate valves usually have rising stem structure with one-piece body. The position of th stem helps

        in identifying whether the valve is in closed or open position. Since the forgings have perfect mechanical

        and chemical properties in comparison with castings, the forged gate valve is mainly used in high 

        pressure and high temperature services covering a small size range.

    2. Material Specification:

        Body & Bonnet : A105, LF2, F11, F22, F304/F304L, F316/F316L, F51

        Seat Ring: AISI 410, 410+HF, SS 304/304L, SS 316/316L, F51

        Wedge: F6a, F6a+HF, F304(L), F316(L) 

        Stem & Gland: AISI 410, F304(L), F316(L), F51;   Bolts & Nus: B7/2H B8M/8M

        Handwheel: ASTM A197, Packing: Flexible Graphite

    3. Size and Pressure Ratings:

        1/2" ~ 2-1/2" (DN15 ~ DN65);  150LB ~ 1500LB
