Ball valve is a kind of valve which uses a ball with a circular passage as the closure, and the ball rotates with the stem to realize the opening and closing action. The Closure of the ball valve is a ball with holes, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the passage. The Ball valve is used to on/off the medium in pipeline and is widely used in petroleum refining, chemical, electric power, long-distance transportation pipeline, paper making, pharmaceutical, water conservancy, municipal, steel, etc. Special consideration is taken to strength, safety and resistance to harsh environment during designation. It's suitable for various corrosive and non-corrosive mediums. Different materials may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea. Ball valve has compact structure and reliable sealing. Its sealing surface and spherical surface are closed normally, which make it resistant to flush erosion from the medium and easy to operate and repair.

Ball valve can be divided into floating ball valve, trunnion mounted ball valve, elastic ball valve and oil seal ball valve according to its structure; According to the channel, it can be divided into direct type, angle type and three-way type. And the three-way type can be divided into T-type Ball Valve and L-type Ball Valve. According to the connection, it can be divided into threaded connection, flange connection and welding type.

The main advantages of ball valve are as follows:

1.It is suitable for frequent operation, quick and light to open and close.

2.Low fluid resistance.

3. Simple structure, small volume, light weight and easy maintenance.

4. Good sealing performance

5. It is not limited by the installation direction, and the flow direction of the medium can be arbitrary.

6. No vibration and low noise.

The installation and maintenance of ball valve should pay attention to the following matters:

1. The valve handle rotation position shall be reserved

2. It can't be used for throttling.

3. The ball valve with transmission mechanism shall be installed vertically.
