    A butterfly valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe.
    The valve is similar in operation to a ball valve. A flat circular plate is positioned in the center of the pipe.
    The plate has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the
    plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow,
    therefore a pressure drop is always induced in the flow regardless of valve position.


    Brief introduction:

    Double eccentric end flanged resilient sealing butterfly valve is operated by the disc rotating form

    0° to 90°, can be applied to cut off or regulate the flow of medium.


    Vitreous enamel is available upon request.


    The valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator.


    Widely used for potable water supply and distribution, electric power plant, gas supply, warm-air

    system,

    smelting plant, chemical industry.


    Features:

    Professional design

    When initiating the rotary opening movement the disc is off-seated after only a few

    degree of opening movement and there is very little wear and tear between seat ring and disc.


    Combine fastness

    Stainless steel seat ring is rolled into the valve body by applying special rolling technology

    when DN<1200. Ultrasonic spray applies seal of valve body when DN>1400.


    Adjust tightness

    Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures

    best performance of adjusting the compression of sealing.


    Sealing reliable

    Body and disc made of ductile iron which promote the impact resistance and pressure-bearing

    capacity, sealing ring made of rubber and valve seat’s sealing surface is conical shaped, make the

    sealing capacity more reliable.


    Excellent corrosion protection

    Inside electrostatic epoxy resin power coating or vitreous enamel(upon request), outside electrostatic

    epoxy resin power coating.


    Reliable health nature

    Epoxy resin power is up to the health standard.

    1. BRIEF INTRODUCTION:

    The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate

    the flow of medium.


    The valve can be actuated by operating lever, handle wheel electric actuator or pneumatic actuator.


    Widely used for potable water supply, waste water treatment, electric power plant, gas supply,

    warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.

    6. Operation:

    6.1. The two pipe flange should be smooth.

    6.2. Put the butterfly valve in the pipe line, fixed the orientation hole first.


    7. Delivery:

    When delivery or store the butterfly valve, should keep in dry and cool environment.


    8. Note:

    8.1. Pipe flange should same as the butterfly valve flange.

    8.2. Check the valve before installed, the environment should correspond to the butterfly valve

    specification.
