Performance characteristics of pneumatic ball valve:
1. The pneumatic ball valve has simple structure, small volume and light weight. The sealing surface material of the ball valve is widely used with tetrafluoro, the deposited welding has good sealing performance, abrasion resistance and erosion resistance, and has also been widely used in the vacuum system.
2. The pneumatic ball valve is easy to operate, fast to open and close, and rotates 90 ° from full open to full close for remote control. It is easy to maintain, the pneumatic ball valve is simple in structure, the sealing ring is generally movable, and it is easy to remove and replace.
3. When the pneumatic ball valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when passing through. It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
4. As the power source of pneumatic ball valve is cylinder dependent gas, the pressure of pneumatic ball valve is generally 0.4-0.7MPa. If the pneumatic ball valve leaks, the gas can be discharged directly compared with the hydraulic and electric valves.
5. Compared with manual and turbine rotating ball valves, pneumatic ball valves can be configured with large caliber. Manual and turbine rotating ball valves are generally below DN300 caliber, and pneumatic ball valves can reach a larger caliber.

In addition, when using electric ball valves, we should understand the product characteristics of each type of electric ball valve. For different materials, such as natural gas, food, pipes, etc., the production specifications are different, and the operation methods are obviously different. In these aspects, the functionality of electric ball valves will have different performances. The size of equipment is determined by the different production objects, In addition, the size of material storage and sealing also have a certain impact. Generally, the selection of electric ball valve is the main object that determines the operating performance of the equipment itself.
