It is mainly used for cutting or connecting the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valves, it has the following advantages:
1, small fluid resistance, Q41 floating ball valve is one of the small fluid resistance of all valves, even if it is a reduced diameter ball valve, its fluid resistance is quite small.
2, the thrust bearing reduces the friction torque of the valve stem, which can make the long-term operation of the valve stem balanced and flexible.
3, the valve seat sealing performance is good, the sealing ring made of polytetrafluoroethylene and other materials, the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of medium pressure.
4, the valve stem seal is reliable, because the valve stem only for rotating movement without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.
5, due to the internal polytetrafluoroethylene and other materials have good self-lubrication, friction loss with the ball is small, so the service life is long.
6, the lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
Q641F flanged pneumatic ball valve is a rotary valve with a Angle of 90°, excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance. Products are widely used in chemical, petroleum, textile, electric power, food and pharmaceutical, refrigeration, paper industry system control.
