1. Overview and Application
Pneumatic soft seal floating ball valve has a simple structure. The ball is a floating structure and relies on the single force of the medium acting on the ball to make the ball move closer to the valve seat on one side.
The sealing function is achieved by squeezing the valve seat and is mainly used in low-pressure shutoff situations. This series of valves are ideal products for use as pipeline switches. It has the characteristics of compact
structure, light weight, high circulation capacity, strong cutting performance and long service life. Currently it is the best choice for steam, hydrocarbon, and corrosive media conditions.
