    DS / Z64H Pipeline Cast steel gate valve water sealed by flange and welding

    DS / Z64H Pipeline Cast steel gate valve water sealed by flange and welding


    Chief strucure features and usages

    1.The chamber of packing of the valve's bonnet is of a water-sealed structure, which, when the water of 0.6-1MPa

    pressure goes into the mouthpiec, can make the system isolated from air to ensure the system with

    a good leak proofness

    2.Model S/Z series use dual-gate dual-direction elastic sealings.being flesible and

    fast to open and close, reliable sesling

    3.Simple, compact and reaso able structur, easy to overhaul and long duration

    4.When to be used as the open&close device on pipelines, it must be in fully-opened or fully-closed

    state and unallowed to be used for flow adjustment

    5.Two ways of connection:by flange and welding, two driving ways:manually and electrically

    6.Suitable to act as the open & close device for the pipelines with the working medium of water,

    steam, oil goods and non-corrosive gas, especially for the vacuum condensation system of the

    steam tufbine in steam power palnts
