Introduction of pneumatic ball valve

           Pneumatic valve is coupled with pneumatic actuators which has relatively fast execution speed. The valve is called pneumatic quick disconnect valve due to the fastest switching speed of 0.05 seconds / time. Pneumatic ball valve usually configures various accessories, such as solenoid valves, air FRL, limit switches, positioners, and control boxes and so on. Pneumatic ball valve with these accessories can realize local control and remote central control by door switch and don’t need to go on-site or bring high altitude and risk of manual control. Time, human resources and security can be saved in large measure by this way.

Characteristics and performance of pneumatic ball valve

            Its features: 1. Small hydraulic resistance, especially the ball valve has the smallest hydraulic resistance of all kinds of valves, even for the reduced ball valve.  2. Thrust bearing reduce the friction moment of stem which can makes the valve stem operate steadily and flexibly for long-term. 3. Good seat sealing performance adopts the elastic material such as PTFE to make the seal ring. With the structure which is easy to seal, the sealing ability of ball valve can be better with the medium pressure increases. 4. Reliable stem sealing performance, because the stem only does the reverse rotation movement but not does the lifting movement, the stem packing seal is not easy to be damaged and sealing ability can be better with the medium pressure increases. 5. Because PTFE material has good self lubrication and the loss of ball friction is small, the ball valve has long service life.  6. Anti-static function: setting the spring in the ball, valve stem and body makes the electrostatic derived which is produced in the opening and closing process.
