Q641F flange type high platform pneumatic ball valve

Q641H-16P flange type V-type pneumatic ball valve, Q641 flange type thermal insulation pneumatic ball valve, Q641F pneumatic high platform ball valve, pneumatic high platform fire-proof ball valve, excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure and service life Long; the pneumatic actuator has a good anti-corrosion shell, a visual position pointer display, and the appearance design is light and maintenance-free. The mechanical friction of the actuator is between Ra0.4～0.6, to ensure that the friction is reduced to the minimum value and to ensure the longest life of the actuator. The smooth components ensure low friction rate to avoid friction between metal and metal to extend the working life of the actuator. Each actuator has undergone 100% rotation and sealing tests before leaving the factory, with a service life of more than 1 million times.

Using dewaxing precision casting, fireproof structure design, high platform gauge is easy to install the actuator; there is an anti-static device between the valve stem and the valve body, the valve stem has an explosion-proof outlet device, and the steel ball has a pressure balance hole; double-layer valve stem packing And two disc-shaped shrapnel devices, the valve body has a device for cleaning the valve cavity.

product advantages:

1. The fluid resistance is small, and the ball valve is the smallest fluid resistance of all valves. Even the reduced diameter ball valve, its fluid resistance is quite small.

2. The thrust bearing reduces the frictional torque of the valve stem, which can make the valve stem long-term operation balanced and flexible.

3. The valve seat has good sealing performance. The sealing ring made of polytetrafluoroethylene and other materials is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.

4. The valve stem is reliable in sealing. Because the valve stem only rotates 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.

5. Since materials such as polytetrafluoroethylene have good self-lubricating properties, the friction loss with the ball is small, and the service life of the ball valve is long.

6. The bottom-mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying. 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.
