Butt Weld Ball Valve

About product

The butt-weld ball valve is a highly efficient valve featuring a spherical, closed ball that rotates around the centerline of the body to open and close. Primarily used in pipelines, it facilitates media cutting, distribution, and flow direction alteration.

As a relatively new type of valve, the butt-weld ball valve has gained significant popularity and widespread adoption in various industries in recent years.

  • Efficient flow.
  • Compact and lightweight.
  • Reliable sealing.
  • Convenient 90° rotation for operation.

Product Detail

Firstly, the three-piece welded ball valve offers the following advantages:

1. Minimal fluid resistance, with a resistance coefficient equal to the length of the pipe section.
2. Simple structure, compact size, and lightweight design.
3. Reliable sealing performance, with the use of plastic materials widely for the valve’s sealing surfaces, including in vacuum systems.
4. Convenient operation, with quick opening and closing achieved through a 90° rotation, facilitating remote control.
5. Easy maintenance, thanks to the simple structure and movable seals, allowing for convenient removal and replacement.
6. Effective sealing during full open or closed positions, preventing corrosion of the valve’s sealing surfaces by isolating them from the media flow.
7. Versatile applications, suitable for a wide range of diameters, from small to large sizes, and capable of handling both high vacuum and high-pressure conditions.

Secondly, the three-piece ball valve features and uses include its primary function of cutting off or connecting pipelines, as well as fluid regulation and control. Compared to other valves, it offers the following advantages:

1. Minimal fluid resistance, making it the most efficient option among similar valves, even in reduced-diameter configurations.
2. Reduced friction torque due to stem thrust bearings, ensuring smooth and flexible long-term operation.
3. Excellent valve seat sealing performance, utilizing elastic materials such as PTFE for easy and reliable sealing, with sealing capacity increasing under higher media pressure.
4. Reliable stem seal, as the stem only rotates without lifting, reducing the risk of packing seal damage and enhancing sealing capacity with increased media pressure.
5. Long lifespan due to the ball’s low friction loss, thanks to self-lubricating materials like PTFE.
6. Enhanced stem seal through the lower stem and stem stem design, preventing protrusion and ensuring metal contact with the valve body to maintain effective sealing even in case of a fire.
7. Anti-static function provided by a spring between the ball, valve body, and the discharge of static electricity during switching processes.
