Stainless steel ball valves can be opened and closed easily only by rotating 90 degrees. They can be used to control the various corrosive media flow such as water, steam, air, slurry, oil and liquid metal. These valves include
pneumatic stainless steel ball valves, electric stainless steel ball valves, stainless steel manual ball valves, etc. And this article will discuss the
pneumatic stainless steel ball valves.
Applications of pneumatic actuated stainless steel ball valves
The
ball valve is equipped with a pneumatic actuators which has fast execution speed, saving human resources and time for workers to operate the device themselves. Its working principle is to make the valve open or closed by rotating the valve core (a hollow ball).
The
pneumatic actuated stainless steel ball valve has been widely used in petroleum, chemical industries, power generation, papermaking, atomic energy, aviation, rocket and other fields. And its diameter ranges from a few millimeters to several meters, so it can be applied to high vacuum and high pressure applications. Both ball valves and plug valves belong to quarter-turn valves, except that the closure member of the ball valve is a hollow ball which rotates around the center line of the valve body to open or close the valve. In the pipeline, the ball valve is mainly used to cut off, distribute and change the flow direction of the medium.
Advantages of stainless steel pneumatic actuated ball valves
1. The fluid resistance of
stainless steel pneumatic ball valves is small, and their drag coefficient is equal to that of the pipe section with the same length as them.
2. Small size and light weight.
3. Good sealing performance.
4. Convenient operation. Quick opening and closing. (these ball valves can be fully open or closed only by rotating a quarter turn and are convenient for remote control.)
5. Simple structure and easy maintenance. (The sealing ring is generally movable, so it can be easily disassembled and replaced.)
6. When the valve is fully open or closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, which will not cause erosion of the sealing surface of the seat if the medium passes.
7. A wide range of applications. (Diameters ranges from a few millimeters to several meters. Thus, applications of the ball valve can range from high vacuum to high pressure.)
