    Floating ball Chart



    1, in a variety of valves, Floating Ball Valves Which ball valve minimum flow resistance, at full bore ball valve open, the ball passage, the valve body and the connection channel and into a diameter equal to the diameter of the media is almost no loss of flow through

    2, the rotary valve is fully closed to fully open 90 °, open and close quickly. With the same size valve, the valve compared to the ball valve, small size, light weight, easy to install pipes

    1, advanced Seat: poly many years experience in manufacturing ball valve seat designed to ensure that the valve seal, low friction coefficient, low operating torque, a variety of seat materials, wide.

    2, the switch handle unmistakable: The flat head stem, and is not connected to the handle dislocation, thus ensuring the switching status of the valve handle indicates a speech.

    3, the locking device: To prevent misuse valve switch, the valve is fully open, fully closed position with a lock hole, ensure that the valve is in the correct position.

    4, stem anti-fly structure: stem to download formula to prevent fly compression, while after the fire, and the body formed metal contact, to ensure that the valve stem seal.

    5, the ball is a sphere with a circular through-hole as the opening and closing pieces, the stem driven sphere around the stem Centres 0 to 90 degree rotation, complete opening and closing function; compact switch having the characteristics of rapid rotation 90 degrees, you can close the valve, cut off line media; the same sphere passage diameter pipe diameter, low flow resistance, flow capacity; the stem as download type, to eliminate the stem piercing accidents, ensure the safe use .

    Suitable medium: water, gas, oil, natural gas and acid-base corrosive media.
    Temperature: -196 ~ 350 ℃
    Drive mode: manual, pneumatic, electric, hydraulic, and so on.
    Nominal diameter: DN 15-250 1/2 "~ 10

    Floating Ball Valves reviews

    Floating Ball Valves Which ball valve is floating in the medium under pressure, the ball can produce some displacement and pressed against the sealing surface of the outlet end, the outlet end of the guarantee seal.

    Floating ball valve of simple structure, good sealing, but the ball all bear the load of the working medium to pass the exit ring, so to consider the ring material can withstand sphere medium work load, in shock when subjected to high pressure , the ball may be shifted. This structure is generally used in low-pressure valve.

    The main features of valve is its own compact, reliable sealing, simple structure, easy maintenance, spherical surface and seal often in the closed state, can not easily be medium erosion, easy operation and maintenance, general working water, solvents, acids, and natural gas is suitable for media, but also applies to the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene in various sectors has been widely used. Ball valve can be integral, it can also be modular.
