1, fluid resistance small, pneumatic ball valve of all categories of least resistance in a fluid, even reduced diameter pneumatic valve, the fluid resistance is quite small.
2, the stem thrust bearing reduces friction torque, smooth operation can stem the long-term flexibility.
3, the seat sealing performance, the use of Teflon and other seals made of elastic material, the structure easy to seal, and the pneumatic valve of the valve closure increased capacity with medium pressure increases.
4, stem seal, reliable, turning the stem only for transportation and do not do fake down movement, not easy to damage the valve stem packing seal, and sealing ability increased with the increase of the pressure medium.
5, the PTFE and other materials have good self-lubrication, the friction loss is small and the ball, so the pneumatic valve for long life.
6, download-type stem and stem head convex order to prevent the exhaust valve stem, stem seal damage, such as fires, convex order and the body can form a metal contact, to ensure that stem seal.
7, anti-static function: the ball valve, valve body is placed between the springs, can export the generation of static electricity switching process.
