ball valves can divide into many types. 1. Metal material valve: carbon steel valve, alloy steel valve, stainless steel valve, titanium alloy valve, aluminum alloy valve and so on. 2. The lining valve of metal valve body: valve lining with rubber, valve lining with fluorine, valve lining with plastic and so on. 3. The non-metal material valve: cermic valve, glass valve and so on.
ball valves.
The ball valves in domestic are produced as standards; they can divide into many types.
1.Ball valves with floating ball. The sphere of ball valves is floated. Under the function of medium's pressure, the ball will have displacement and press tightly on the sealing side of exit end. The structure of these ball valves is simple and the sealing performance is good.
2.Ball valves with fixed ball. The ball is fixed, while the valve seat is floated. With the pressure of medium, the valve seat will moved and the seal rings press tightly with the ball to ensure the sealing.
3. Ball valves with elastic ball (tract ball valves). The ball is elastic. The ball and seal ring of valve seat are made by metal material. The sealing specific pressure is very big, it can not meet the needs of sealing with the own pressure of medium.

Introducing the classifications of ball valves is to help you to choose the most suitable one for you working.

At present, the ball valves manufactures in domestic are following the standards of JB/T2203-1999 the structure length of ball valves. Here are the classifications of ball valves.
1. V type ball valves. These kinds of ball valves are belonging to fixed ball valves; also belong to sealing ball valves with single valve seat. The adjust performance is the best among all ball valves. The V type ball valves are most suitable for the medium containing fiber, small solid particles and slurry.
2. three-way ball valves. The three-way ball valves have T type and L type. T type can cut one of the pipelines and make another two pipelines connecting. It has an impact of distribution and confluence. L type can only connect two pipelines and only plays a role of distribution. The structure of three-way ball valves is integration, so the reliability is high and the design weight is light.
3. Decentered ball valves. The decentered ball valves have many advantages: the hydraulic resistance is small; the structure is simple, the volume is small and the weight is light; the operation is convenient; the maintenance is convenient; the using is extensive.
After understanding the details of different ball valves, you can choose the most suitable ball valves.
