BALL VALVE

Ball valve and plug valve is the same type of valves only its closure of a spheroid,spheroidaround a rotary axis lines to achieve valve body opened and closed a valve.

Ball valve used to be cut off in the main line,distribution and change the direction ofthe flow medium.Ball valve is widely used in recent years a new type of valves,it hasthe following advantages:

1. Ball valve fluid resistance small,and its resistancecoefficient with the length of the barrel of equivalent.

2. Bal1 valve structure simple,small size,light weight,

3. Ball valve closely reliable,current Ball valve sealed surfacematerial widely used plastic,undergo good in a vacuum system also has been widely used.

4.Ball valve easy to operate,the closing rapidly,from open all around,as long as there

90E,facilitate remote control.

5.Ball valve maintenance convenience Ball valve structuresimple,seal ring generally activities,the removal of the replacement is more convenient.

6.Ball valve whole or in the open all closed,spheroid and the sealed surface with mediumvalve seat separation medium through,will not cause the valves sealed surface erosion.

7.Ball valve application scope Link Drive from small to several millimetres,a few metersin from the high pressure can be high vacuum applications.
