The advantages of the electric flanged ball valve
Addtime：2023-08-16 From： View：462
The electric flange ball valve is a ball valve equipped with an electric actuator. The actuator of the electric actuator has a relatively fast operating speed and does not require workers to operate manually. This greatly saves human resources and time. The electric flange ball valve has the same 90-degree rotation action. It has a circular hole or passage passing through its axis. The ratio of the spherical surface and the passage opening should be such that when the ball rotates 90 degrees, the entire spherical surface should be presented at the inlet and outlet, thereby cutting off the flow.
The electric flanged ball valve is mainly used for cutting off or connecting the medium in the pipeline. It can also be used for regulating and controlling the fluid. Compared with other types of valves, it has the following advantages:
1. Low fluid resistance. The ball valve has the lowest fluid resistance among all types of valves. Even the reduced-diameter ball valve has relatively low fluid resistance.
2. The thrust bearing reduces the frictional torque of the valve stem, enabling the valve stem to operate smoothly and flexibly for an extended period of time.
3. The valve seat has excellent sealing performance. The sealing ring is made of elastic materials such as polytetrafluoroethylene. The structure is easy to achieve sealing, and the sealing capacity of the ball valve increases as the medium pressure rises.

5. Due to the excellent self-lubricating properties of materials such as polytetrafluoroethylene, there is minimal frictional loss between the ball and the valve body, thus resulting in a long service life of the ball valve.
6. The lower-mounted valve stem and the raised step at the head of the valve stem prevent the valve stem from spilling out. In case the valve stem seal is damaged due to a fire, the raised step can still form a metal contact with the valve body, ensuring the valve stem seal.
7. Anti-static function: Springs are installed between the sphere, the valve stem, and the valve body, which can discharge the static electricity generated during the switching process.

4. The valve stem has a reliable seal. Since the valve stem only undergoes rotational movement and not vertical movement, the packing seal of the valve stem is less likely to be damaged, and its sealing capacity increases as the pressure of the medium increases.
