Purpose and features：
BR.W81 series O type ball valve is one kind of straight through ball valves. It can switch from fully open to fully close or from fully close to fully open by only 1/4 turn of the ball around the rotation axis.
This series of ball valves have excellent cut-off performance. When fully opened, the flow path and the inner diameter of the pipeline are basically the same, and the fluid pressure loss is very small, so it is most suitable for cut-off control of various liquids, gases, slurries and other fluids.
1. O-ball valves can be divided into floating ball valve, fixed ball valve and fluorine lined ball valve. There are two types of seal, soft seal and metal seal, which have excellent cutting performance.
2. The valve has the advantages of simple structure, small volume, smooth flow passage, small flow resistance, large flow capacity and no flow direction requirement for medium.
3. The switch is fast, the ball only needs to rotate 90 ° to complete the full open or full close action, and it is easy to realize the quick opening and closing, so it is easy to realize the automatic control and remote control；
4. The ball valve with fluorine lining has strong corrosion resistance and excellent sealing performance, which can cut off the corrosive medium such as acid, alkali and salt in the production process.
