美国进口派克高压球阀在管路中主要用来做切断、分配和改变介质的流动方向。球阀是近年来被广泛采用的一种新型阀门，它具有以下优点：
1． 流体阻力小，其阻力系数与同长度的管段相等。
2． 结构简单、体积小、重量轻。
3． 紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
4． 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
5． 维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
6． 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
7． 适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

US imports Parker high-pressure valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow. Ball is a new valve has been widely used in recent years, it has the following advantages:
1. Fluid resistance, the pipe resistance coefficient equal to the same length.
2. Simple structure, small size and light weight.
3. Close and reliable valve sealing surface material widely used plastic, sealing, have 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 90 °, to facilitate remote control.
5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.
6. In the fully open or fully closed, 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 to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied.
