Pneumatic thread The ball valve is flexible. Ball and the valve seat ring made of metallic materials, sealing pressure greatly rely on the pressure of the medium itself has reached less than sealing requirement s, you must apply force. This valve is applicable to high temperature and pressure medium. Elastic sphere is the bottom of the sphere wall to open a flexible tank, to obtain flexibility. When the channel is closed, the wedge-shaped head of the stem so that the sphere up on compression to seal with the valve seat. To release the wedge-shaped head before rotating sphere, the sphere followed by restoration of the original prototype, a small gap between the ball and valve seat sealing surface can reduce the friction and operating torque. Pneumatic threaded ball valve according to the position of the channel can be divided into straight-through, three links and rectangular Type. The latter two ball valves for the distribution media and change the flow of media.
