The advantages of ball valves
Ball valve and plug valves are belonging to the same type of valve, the
only difference is that ball’s shut down parts is sphere. The sphere rotates around the center line of valve to achieve the goal of
opening and closing. Ball valve is mainly used to cut，distribute and change the direction of media flow. Ball valve is a new type of valve
which is widely used in recent years. It has the following advantages:
1. Less fluid resistance. The resistance coefficient is equal
to the tabulation when they have the same length.
2. Simple structure, small size and light weight.
3. Close and reliable. Ball
valve‘s surface material is widely used in plastic industry and vacuum system.
4. Its Easy to operate, opening and closing rapidly.
It just as long as the rotation 90 °from fully open to fully closed. And it also provide more convenient for remote control.
5. It’s
easy to repair. Ball valve has a simple structure and its sealing ring is generally active. All of them also leave convenient for removal
replacement
6. In the fully open or fully closed, the body and the seat’s sealing surface of valve were isolated the medium. So, even
when the medium through, it will not cause erosion of the valve sealing surface.
7. Wide range of applications. Its diameter has a
wide range from small to a few millimeters to several meters. So it can even be widely used in high vacuum and high pressure.
Now, ball valve has been widely used in petroleum, chemical, power generation, paper, nuclear,
aviation, rockets and other departments, as well as people’s daily lives.
