Fully Welded Ball Valve

Fully Welded Ball Valve
Why are all the valves
on pipelines nowadays using fully welded ball valves?
The fully welded ball valve adopts full welding technology to weld all the gaps on the surface of the valve body to ensure that there is no leakage point in the entire valve body. It has the characteristics of simple structure, small size and light weight. And the main point is that it uses seamless welding. Fully welded and compact, able to withstand higher pressures. Another point is that the valve body is symmetrical and uses a combination of CNC and manual welding to ensure zero external leakage. The valve can be buried underground and has the characteristics of anti-infiltration.

Why Choose Lipin's Fully Welded Ball Valve

Lipin fully welded ball valves are manufactured by pressing seamless steel pipes. This manufacturing method is just right to maintain good sealing of all welded ball valves. The reason is that it is difficult to press seamless steel pipes, and it is impossible to ensure uniform stress after installation. Because the installation environment of the fully welded ball valve is inspected before manufacturing, and the same material as the piping system is selected to suppress the fully welded ball valve, so after the manufacturing is completed, the fully welded connected valve is made of the same material as the piping system, so The force is uniform, so there is no failure of the valve to be damaged due to uneven stress. Valve leakage is greatly reduced.
  • Fully welded sealing design
    The unique full welding process welds all the gaps on the surface to prevent internal and external leakage through the gaps.
  • A variety of materials to choose from
    Beyond traditional carbon steel, we offer avant-garde options such as Inconel and Monel. Such materials serve as a bulwark against corrosion, especially in challenging environments.
  • Wide range of applications
    Whether it is used in thermal oil, thermal power plants or gas output, the fully welded ball valves produced by Lipin can be perfectly adapted.
  • The quality is high enough
    For each process, we are operated by specialized welders. Each welder needs to hold a welding certificate to work. The full welding machine also uses the most advanced CNC machine to ensure the accuracy of processing.
  • Multiple operating modes to choose from
    electric, pneumatic, hydraulic, manual operation, and gearbox drive is the most popular option.
  • 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 Fully Welded Ball Valves

The fully welded ball valve mainly consists of the following six parts. This component ensures that the fully welded 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

    Fully Welded Ball Valves

    • 01
      High-end self-sealing design
      The higher the pressure, the more reliable the seal and the better the usage characteristics. It has properties such as high temperature resistance and corrosion resistance.
    • 02
      When fully open and fully closed
      When fully open and fully closed, the sealing surface of the ball and valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.
    • 03
      With compact structure and light weight
      With compact structure and light weight, it can be called the most reasonable valve structure for low-temperature medium systems.
    • 04
      Ball valves with fully welded valve
      Ball valves with fully welded valve bodies can be buried directly in the ground to prevent internal parts of the valve from being corroded. The longest service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines.
    • 05
      The fully welded ball valve
      The fully welded ball valve adopts a fixed ball structure. Even if the pressure is unstable, the valve can still ensure tightness.

    Why Choose Fully Welded Ball Valves?

    The fully welded ball valve seat is made of polytetrafluoroethylene rigid seal material and spring, so the ability to adapt to changes in pressure and temperature is very strong, and the fully welded ball valve ensures that there will be no leakage within the labeled pressure and temperature range. Due to the whole welded design, the flange and bolt on the valve body are removed, there is no leakage of parts, and the valve can be directly buried underground, saving space and reducing the risk of leakage.

    About Lipin Fully Welded 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 hard-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.
