Pneumatic ball valves are widely used in natural gas, oil, chemical, mining and other industries to control and adjust the flow of the medium, which can be used with automatic pneumatic instruments.

The ball of the pneumatic ball valve is elastic, not very hard. Its ball and seat sealing ring are made of metal materials, if the inch only relies on its own pressure to pressure it is unable to meet the requirements of the seal, this must be applied external force to achieve the requirements of the seal. Pneumatic ball valve is more suitable for high temperature and high pressure media.

Pneumatic ball valve ball is elastic he relies on the inner wall of the ball will be opened at the lower end of an elastic slot. When the channel is closed, the wedge head on the stem can be used to allow the whole ball to expand and press its seat to produce a seal effect.

The use of pneumatic ball valves in industry is to adjust the flow direction of the medium. Then his tight sealing performance is also used which is more desirable.
