Floating Ball Valve

Floating Ball Valve
How does a
floating ball valve achieve high strength sealing?
The ball of the valve can float. The ball valve squeezes the middle ball core through the seat sealing rings on both sides of the inlet and outlet. When the stem is rotated, the ball rotates freely between the two seat sealing rings with the help of the valve stem, achieving the opening and closing action of the floating ball valve. Under the action of pressure and fluid, the seat of the sphere flowing towards the medium is sealed and compressed to achieve a sealing effect. The higher the pressure, the better the sealing.

Why Choose Lipin's Floating Ball Valve

Lipin's floating ball valve has small volume, light weight, simple structure, and free floating function, which can ensure good sealing; The ball valve uses a sphere with a circular through-hole as the opening and closing component. Under the drive of the valve stem, the sphere rotates 0-90° around the center of the valve stem to complete the opening and closing function.
  • Anti valve stem wear design
    The pressure plate and pressure sleeve are in spherical contact to ensure that the pressure sleeve is always vertical. A PTFE liner is installed inside the pressure sleeve to avoid wear of the valve stem and pressure sleeve, and to reduce the operating torque of the valve.
  • Unlimited material selection
    Apart from traditional carbon steel, we also provide more advanced material, like Inconel and Monel, to prevent valve corrosion.
  • Visible in all fields
    Lipin's floating ball valve are perfectly suitable for all fields such as natural gas, chemistry, and power plants, playing an important role.
  • Stick to high quality principle
    We choose high-quality raw materials to ensure consistent product quality. Each floating ball valve undergoes rigorous testing and quality inspection to manifest its excellent performance.
  • Multiple operations
    According to your choice, we can match manual, worm gear, pneumatic actuator, electric actuator and hydraulic actuator.
  • Top service team
    Our company's one-stop valve solution helps our customers solve many concerns and troubles. Not only that, we also provide a two-year warranty for our products. If you are interested, you can contact us to get a plan.

Key Components of Floating Ball Valves

The floating ball valve mainly consists of the following six parts. This component ensures that the floating ball valve remains efficient and stable during operation and maintains a zero leakage record.
  • Valve Body
    Guides the flow of media.
  • Sphere
    The medium passes through or is intercepted by the sphere.
  • Valve stem
    Drives the ball to open and close quickly through 90° rotation.
  • Valve seat
    Contact with the ball to form a seal.
  • Sealing surface
    Soft seal and metal seal.
  • Actuator
    The movement of a valve that controls the valve stem.
  • Advantages of

    Floating Ball Valves

    • 01
      Quick response
      The diameter of the entire channel of the floating ball valve is consistent with the pipeline, so the medium flows very smoothly without any resistance. It can be completely closed by rotating 90°, and the opening and closing are very convenient and fast.
    • 02
      Advanced valve seat
      Lipin has gathered many years of ball valve manufacturing experience and designed the valve seat, to ensure that the valve seal, low friction coefficient, small operating torque, a variety of valve seat materials and wide range of adaptation.
    • 03
      Locking device
      The floating ball valve has locking holes in the fully open and fully closed positions of the valve, reducing the impact of misoperation on valve opening and closing, and avoiding valve opening and closing caused by random touch.
    • 04
      Anti flying structure
      The valve stem is generally bottom mounted, which can effectively prevent the valve from flying out under pressure. And this structure is made of metal material, which can ensure the sealing of the valve stem in case of fire or high-temperature operation.
    • 05
      Good sealing performance
      There is almost no leakage of medium during use, especially when transmitting gas, the floating ball valve has a very good throttling effect on gas.

    Why Choose Floating Ball Valves?

    Lipin's floating ball valve is mainly used in pipelines to cut, distribute, and change the direction of medium flow. The ball has no supporting axis and is clamped by two seats and in a floating state. The ball valve owns reliable reverse sealing valve sealing rod, fire and static electricity prevention function, automatic pressure relief and locking device. The sealing surface and spherical surface are often in a closed state and are not easily eroded by the medium.

    About Lipin Floating Ball Valve

    • Valve Body Type :
      Ball
    • Valve body material:
      Cast WCB carbon steel (general application), forged A105 carbon steel (general application), 304/316 stainless steel, alloy (corrosion resistance, extreme conditions), etc.
    • Valve stem material:
      When the valve body material is ordinary carbon steel, the valve stem material is usually CR13 series martensitic stainless steel (American standard 410 and 420 stainless steel materials) or higher-grade austenitic stainless steel materials. When the valve body material is stainless steel, the valve stem material is usually austenitic stainless steel (American standard SS304, SS316) with a grade no lower than the valve body material and a higher grade corrosion-resistant alloy material (Hastelloy, Monel, Inconel alloy) etc.
    • Valve ball material:
      The valve stem material is basically the same as the valve ball, plus carbon steel electroplating ENP anti-corrosion material, unless there are special requirements.
    • Seat material:
      The metal-sealed metal valve seat and fixed soft-sealed valve seat support ring of the ball valve should be made of the same material as the ball.
    • Seat sealing surface material:
      The valve seat material is basically the same material as the ball, except for special requirements.
    • Pressure level:
      Class 150-2500(ASME standards)or PN10~PN420
    • Actuator:
      Manual handwheel, electric actuator, pneumatic actuator, hydraulic actuator
    • Size:
      1/2'' to 60'' (DN 15-1500)
    • Temperature:
      Depending on the material used, operation can occur within a temperature range of -50°C to +400°C, although specific materials may alter this range.
