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.
