  Three piece butt welding ball valve and flange gate valve belong to the same type of valve. The difference is that its closing part is a sphere. The sphere rotates around the center line of the valve body to open and close. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Two piece ball valve and three piece ball valve are widely used as a new type of valve. Generally, this type of valve should be installed horizontally in the pipeline

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.
2. The utility model has the advantages of simple structure, small volume and light weight.
3. Tight and reliable, the sealing surface of ball valve is widely made of plastic, with good sealing performance, and has been widely used in vacuum system.
4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.7. It has a wide range of applications, ranging from small to several millimeters and large to several meters. It can be applied from high vacuum to high pressure

   The ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valves, it has the following advantages.

1. The fluid resistance is small. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has a very small fluid resistance.

2. The thrust bearing reduces the friction torque of the valve stem, which can make the long-term operation of the valve stem stable and flexible.

3. The valve seat has good sealing performance. The sealing ring made of PTFE and other elastic materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure.

4. The valve rod seal is reliable. Because the valve rod only rotates without lifting, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of the pressure of the medium.

5. As Teflon and other materials have good self lubrication and small friction loss with the ball, the service life of the ball valve is long.

6. The lower mounted valve rod and the convex step at the head of the valve rod prevent the valve rod from ejecting. If the valve rod seal is damaged by fire, metal contact can be formed between the convex step and the valve body to ensure the valve rod seal.

7. Anti static function: a spring is set between the ball, valve rod and valve body to export the static electricity generated during the switching process
