Product Overview
High-performance ball valves are mainly used to cut off or connect the medium in pipelines and can also be used for fluid regulation and control. Among them, the hard-sealed V-port ball valve has a strong shearing force between its V-shaped ball core and the metal seat with weld-overlaid hard alloy, making it particularly suitable for media containing fibers and tiny solid particles. Multi-way ball valves can not only flexibly control the merging, diverting, and flow direction switching of the medium in pipelines but also close any one channel while connecting the other two. Valves of this type should generally be installed horizontally in pipelines.

Working Principle
The high-performance ball valve features a 90-degree rotation action. The plug body is a sphere with a circular through-hole or passage along its axis. In pipelines, ball valves are mainly used for cutting off, distributing, and changing the flow direction of the medium. They only require a 90-degree rotation and a very small torque to close tightly. Ball valves are suitable for use as on/off and shut-off valves, but recent developments have designed them for throttling and flow control purposes, such as the V-port ball valve.

The main features of high-performance ball valves are their compact structure, reliable sealing, simple design, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, making them less susceptible to erosion by the medium. They are easy to operate and maintain and are suitable for general working media such as water, solvents, acids, and natural gas. They are also suitable for media under harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene, and are widely used in various industries. The valve body can be either integral or combined.

Advantages of High-Performance Ball Valve

1. Low fluid resistance. A full-bore ball valve basically has no flow resistance.

2. Simple structure, small size, and light weight.

3. Tight and reliable. It has two sealing surfaces, and currently, various plastics are widely used as sealing surface materials for ball valves, providing good sealing performance and achieving complete sealing. It is also widely used in vacuum systems.

4. Convenient operation, fast opening and closing. It only takes a 90° rotation from fully open to fully closed, facilitating remote control.

5. Convenient maintenance. The ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively easy.

6. When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, so the medium will not cause erosion to the valve's sealing surfaces when passing through.

7. Wide application range. Nominal diameters range from a few millimeters to several meters, and it can be applied from high vacuum to high pressure.

8. Because the ball valve has a wiping action during the opening and closing process, it can be used in media containing suspended solid particles.
