Pneumatic three-piece ball valve is used to cut off or connect the medium in the pipeline in various pipelines with working temperature ranging from – 29 30 C. It can be used in water, steam, oil, nitric aceti and other media with different materials. Pneumatic three-piece ball valve is a new type of valve. It has some unique advantages of its own structure. The switch has no friction, the seal is not easy to wear and tear, and the opening and closing moment is small.
