First, Flange-lined fluorine pneumatic ball valve overview
Pneumatic flange ball valves are ball valves with pneumatic actuators. Pneumatic actuators perform relatively quickly, saving human resources and time to a large extent. Pneumatic flange ball valves are evolved from shut-off valves. It has the same 90 degree lift action, except that the plug body is a sphere with a circular through hole or passage through its axis. The ratio of the spherical surface to the passage opening should be such that when the ball is rotated 90 degrees, the spherical surface should be present at the inlet and outlet, thereby cutting off the flow.
Second, the flanged lining fluorine pneumatic ball valve features
Pneumatic flange ball valves are mainly used in the pipeline to cut off quickly, distribute and change the flow direction of the medium. Pneumatic ball valve is a new type of valve widely used in recent years, which has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. Simple structure, small size and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastics and has good sealing performance. It has also been widely used in vacuum systems.
4. It is easy to operate, and it can be opened and closed quickly. It can be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
5. Convenient maintenance, pneumatic ball valve structure is simple, the sealing ring is generally active, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the sealing surface of the valve.
