Does Chengdu electric fluorine lined wafer butterfly valve need oiling? Because the ball valve has very little resistance to the fluid itself, it can quickly close and open the switch, which is very convenient. The sealing of the pneumatic high-pressure ball valve is also very good. The ball valve can be used for a long time without damage, which has a very high reliability. In addition, the inner pipe of the valve body of the ball valve is very smooth, It is very suitable for the transportation of viscous liquid and other fluids, and has a very good effect on the transportation of solid particles and various slurries. Therefore, ball valves are now widely used
、 If we want to buy high-quality pneumatic butterfly valves, we must do a good job in the selection before buying pneumatic butterfly valves. If the selection is not good enough, many problems will continue to arise. Even if we buy expensive pneumatic butterfly valves, as long as the model is not suitable, many work will be wasted. So how to do a good job in type selection?
