    Features & Benefits

    SG41 has compact structure, small flow coefficient, reliable sealing, light & flexible operation and long service life. Its sealing surface is made of stainlesss steel & cemented carbide, and the uppper seal is flexible graphite filler.

    Flanged Wedge Gate Valve SG41

    The ductile iron handwheel is more durable. The right size makes the handwheel rotate more labor-saving.

    The stem bushing acts as a support for the handwheel and drives the stem to rotate through the internal thread to lift the disc. Bronze and steel can be selected by requirements.

    Different materials can be selected according to the working conditions. Hardness and corrosion resistance are the primary considerations.

    Reinforced graphite packing material can effectively enhance the sealing performance of the stem, reduce the openning & closing toque and make the operation more labor-saving.

    As the connection point connecting stem and disc, wear resistance and corrosion resistance are the primary factors in material selection.

    It is wedge-shaped and can be surfacing welding alloy steel.

    A variety of body materials can be selected. The body has a self-sealing structure, and its groove design plays the role of maintaining the disc, making the disc not easy to deform.

    The disc is made of pure metal with high temperature resistance, high processing precision, wear resistance, and the disc does not block the flow channel when fully opened.

    The hard metal-to-metal sealing seat can be applied to high temperature and high pressure medium. The seat can be surfacing welding alloy steel or other materials with high wear resistance and corrosion resistance.
