The ball of pneumatic titanium ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure the sealing of the outlet end.

1. Pneumatic titanium ball valve has small flow resistance. The ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has relatively small fluid resistance.

2. Good sealing performance. The valve seat (seal ring) of the ball valve is generally made of PTFE, polytetrafluoroethylene and other elastic materials, which is easy to ensure sealing, and the sealing force of the ball valve increases with the increase of medium pressure.

3. The valve rod of pneumatic titanium ball valve is sealed reliably. When the ball valve is opened and closed, the valve rod only rotates by 90 °, so the packing seal of the valve rod is not easy to be damaged, and the sealing force of the reverse seal of the valve rod increases with the increase of the medium pressure.
