In this catalogue, you will find all datasheet for Electric flanged ball valve , including material, dimension, assembly drawing, working temperature, nominal size, pressure rating.

Electric flanged ball valve is that it has the same lifting action of rotating 90 degrees and has a circular through hole or channel through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, all spherical surfaces should be present at the inlet and outlet, thereby truncating the flow.

The electric flanged ball valve only needs to be operated by rotating 90 degrees with air and a small torque can be closed tightly. The completely equal valve body cavity provides the medium with a small resistance and straight-through flow channel, which is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, Methane and Ethylene etc.

1. Small fluid resistance, ball valve is the smallest fluid resistance among all valves, even the 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 valve stem operate smoothly and flexibly for a long time.

3. The valve seat has good sealing performance. The sealing ring made of elastic materials such as PTFE is easy to seal in structure, and the sealing ability of the ball valve increases with the increase of the medium pressure.

4. 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 ability increases with the increase of the pressure of the medium.

5. 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.

6. 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.

7. Anti-static function: A spring is set between the ball, the valve stem and the valve body, which can export the static electricity generated during the switching process.
