DN1200 Flange Butterfly Valve with Supporting Legs

 Usually when the nominal size of the valve is greater than DN1000, our valves come with support legs, which makes it easier to place the valve in a more stable way. Large diameter butterfly valves are usually used in large diameter pipelines long with you over to control the opening and closing of fluids, such as hydroelectric power stations, hydraulic stations, etc.

    Product Description

    Pipelines, especially those used for severely corrosive media such as hydrofluoric acid, phosphoric acid, chlorine, strong alkalis, aqua regia and

    Other highly corrosive media.

    Small size, easy to install.
    4-level load elastic seal absolutely guarantees zero leakage inside and outside the valve.

    This product is used for the water supply and drainage system in tap water, sewage, building, chemical etc. industries, usually used as an open-close equipment.

    Butterfly valves are like ball valves but have more advantages. They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.

    It can be used for transmitting mud, fewer liquids are stored at apertures of pipe.

    Long service life. Standing the test of tens of thousands of opening/closing operations.

    Butterfly valves have excellent regulation performance.

    Body Test: The valve body test use 1.5 times pressure than standard pressure. The test should be done after installation, the valve disc is half close, called body pressure test. The valve seat uses 1.1 times pressure than standard pressure.

    Special Test: According to customer’s requirement, we can do any test you need.

    Suitable Media: Wafer and other neutral medium, working temperature from -20 to 120℃, the application of the valve can be municipal construction, wafer conservancy project, water treatment etc.
