Pneumatic ball valve can be divided into O-type ball valve and V-type ball valve. The O-type ball valve is of floating structure, the ball core is precision casting, the surface is plated with hard chrome, the valve seat is made of reinforced polytetrafluoroethylene material, the flow port is the same as the pipe diameter, the flow ability is great, the flow resistance is very small, and there is no leakage when closing. It is generally used as an on-off valve, especially suitable for high viscosity V-type ball valves. The V-type ball valve is of fixed structure, and the ball core is opened with V-type blocking, Pneumatic or electric actuators can be selected according to different process equipment to complete shearing of fibrous and granular media, and separate them into pneumatic ball valve and electric ball valve. In the meantime, if the pneumatic ball valve needs to complete proportional scheduling, it must be equipped with valve positioner. If it needs to complete proportional scheduling, it must be equipped with electric actuator or servo amplifier.

On the one hand, it is necessary to make its valves achieve good accuracy, and its accuracy performance can reach the best performance when its products are used, so this is the biggest advantage of its own use, and this is naturally because the electric ball valve has reached its own advantage. On the other hand, It can make itself achieve the maximum corrosion resistance in products, which is also an important reason for adapting to chemical industry.
