High pressure ball valve is a relatively new type of ball category , it has its own unique structure of some advantages, such as switches without friction , sealing easy to wear, a small opening and closing torque . Such actuators can be reduced with the specifications. With multi-turn electric actuators , can be realized on media regulation and tight cut . Widely used in petroleum, chemical, water supply and drainage and other cities demanding cutting conditions.
Manual valve in the pipeline is mainly used for cutting, distribution and change the flow direction of the medium. Ball is a new type of valve is widely used in recent years , it has the following advantages:
1 . Fluid resistance , its drag coefficient with the same pipe length equal.
2 . Simple structure, small size, light weight.
3 . Close and reliable valve sealing surface material widely used plastic , sealing, has also been widely used in the vacuum system .
4 . Easy to operate, opening and closing rapidly , from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control .
5. Easy maintenance , simple High pressure
ball valve , seals are generally activities , removal replacement is more convenient.
6. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat , through the media , will not cause erosion of the valve sealing surface.
7 . Wide range of applications , from small diameter to a few millimeters to a few meters from the high vacuum to high pressure can be applied . When the ball is rotated 90 degrees , in the import and export of office should be fully rendered sphere , thus cutting off the flow.
