Flange three-piece pneumatic ball valve

1. Three-piece flangePneumatic ball valve overview:

three-piece flange pneumatic ball valve adopts an integrated structure, matching with pneumatic actuators, beautiful appearance, light and cheap, quick disassembly and assembly, flexible operation, simple matching, large circulation capacity, widely used in food, environmental protection, In the industrial automation system of light industry, petroleum, papermaking, chemical industry, electric power and other industries.

2. Features of three-piece flanged pneumatic ball valve:

1. The valve body and end cover are made of dewaxing precision casting  

2. The valve stem is designed to be explosion-proof  

3. The flange connected pipeline can maintain good sealing performance, which is convenient for maintenance and replacement 

4. Full flow diameter floating ball  

5. High platform design adopting ISO5211 to directly install the actuator  

6. Anti-static device between the ball valve and the ball  

7. Double disc-shaped shrapnel automatic compression packing design 

8. Three-piece high platform ball valve is usually used When the pressure and temperature are high, and the sealing requirements are strict. 

9. The sealing surface has self-cleaning characteristics. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through 360° uniformly along the spherical sealing surface, which not only eliminates the partial impact of high-speed fluid on the valve seat Flushing also washes away the accumulations on the sealing surface to achieve the purpose of self-cleaning. Therefore, in addition to controlling gas, liquid, and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. Three.
