Open Spherical Gate Valve

Close
√Specification √Product feature

  • Size：DN250
    Pressures：PN1.6
    Material：WCB
    Temperature ：-40~300℃
    Design：GB

  • 1. When the open-type spherical gate valve closes, there is no relative friction between the disc and the sealing surface of the valve body. The sealing performance is good, the service life is long, and the average service life is several times longer than that of the gate valve.

    2. large circulation area, small flow resistance, high sealing surface hardness.

    3. Valve body and ball valve sealing surface can be surfacing or spraying high hardness, corrosion-resistant alloy materials, can be applied to high temperature, high pressure, low temperature and strong corrosion medium pipeline, its function can completely replace the gate valve.

    4. The valve opening and closing torque is small, only 30% to 50% of the gate valve. The opening and closing time is short, and only 10% to 20% of the gate valves can be quickly closed.

    5. The key to the design of this structure is that it combines the advantages of ball valves and gate valves.
