pneumatic ball Industrial Valves rotates 90 degrees it with the same action, 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 rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow.

love is to rely on the working principle of rotary valve pneumatic ball valve to keep the valve open or closed. 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 valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve.

a, easy to switch quickly to meet on line with quick opening, quick closing high altitude andao requirements

2, fluid resistance small, whether it's reducing ball valve are all full size type Industrial Valves class one fluid of least resistance.

three seating, reliable, ordinary ball seal are tetrafluoroethylene type other plastic better a polymeric material manufacturing, have higher request for seal, soft seal is easier to ensure sealing, metal sealing, & lt; Hard seal & gt; Structure can bear over 10 npa, 16 npa, 32 npa to by high pressure high temperature 350 ℃ in our daily life.

4, reliable stem seal, valve stem's sealing structure can along with the increases with the increment of medium, the denier ball valve open/close the valve stem make rotation movement only, and not of deeds lifting movement. The sealing filler of the valve stem is not easy to damage. The sealing of the Industrial Valves stem significantly longer service life.

5, long service life, pneumatic device in destructive testing more than 60000. Because the sealing parts of ball valve is used more is good self-lubrication material of ptfe gas such as materials and ball valve, the valve stem friction and wear are the youngest, ensure the service life of the valve.
