Pneumatic ball valve is mainly divided intoTwo-way pneumatic ball valve, three-way pneumatic ball valve, four-way pneumatic ball valve, Stainless steel pneumatic ball valve, plastic pneumatic ball valve, sanitary pneumatic ball valve, carbon steel pneumatic ball valve. Compared with others, pneumatic ball valves have the following seven advantages:
1,The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
2,Since PTFE and other materials have good self-lubrication, the friction loss with the ball is small, so the service life of the ball valve is long.
3. Anti-static function: A spring is set between the ball, the valve stem and the valve body, which can export the static electricity generated in the switching process and implement the mechanism.
4.The fluid resistance is small, and the ball valve is the one with the smallest fluid resistance among all valves. Even the reduced-diameter ball valve, its fluid resistance is quite small.
5. The bottom-mounted valve stem and the convex step on the head of the valve stem prevent the valve stem from being ejected. If the valve stem seal is damaged due to fire, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
6.The valve stem is sealed reliably. Because the valve stem only moves in imitation rotation and does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases with the increase of the pressure of the medium.
7.The valve seat has good sealing performance. The sealing ring made of elastic materials such as polytetrafluoroethylene is used for easy sealing, and the sealing ability of the ball valve increases with the increase of the medium pressure.
The above seven points are the advantages of pneumatic ball valves, collect them and forward them~
