Pneumatic ball valve is made by the pneumatic valve

pneumatic ball valve is evolved by the pneumatic valve. It has the same rotation movement, different is the cock body is ball, a circular hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotation, should all present in the inlet and outlet sphere, thus blocking flow. The working principle of pneumatic ball valve by pneumatic valve pneumatic valve love to make smooth rotation or occlusion. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Pneumatic ball valves and cocks pneumatic valve is belong to the same type of pneumatic valves, only its closure is a ball, the ball goes around the center line of the pneumatic valve body for a pneumatic valves to open and close. A, easy to switch quickly to meet on line there is a requirement for quick opening, fast closing high andao place 2, fluid resistance small, whether it's full size reducing type pneumatic ball valve are all pneumatic valve fluid resistance in the smallest one. Three, reliable pneumatic valve seat seal, ordinary ball sealing ring are tetrafluoroethylene type other plastic better a polymeric material manufacturing, have higher request for seal, soft seal is easier to ensure sealing, metal sealing, < > hard seal structure can bear with the Npa, the Npa, the Npa high pressure can be high temperature ℃ in our daily life. Four, reliable pneumatic valve stem seal, can pour sealing structure with the pneumatic valve stem increases with the increment of medium, the denier pneumatic ball valve open/close the pneumatic valve rod make rotation movement only, and not of deeds lifting movement. Pneumatic valve stem packing is not easy to damage. Sealing of the pneumatic valve stem significantly longer service life. Five, the service life is long, pneumatic device in destructive tests above. Because the sealing parts of pneumatic ball valve is used more is good self-lubrication material of ptfe gas such as materials and pneumatic ball valve, pneumatic valve rod friction and wear are the youngest, ensures the service life of pneumatic valve.
