Features
Electric ball valve is mainly used to cut off or connect the medium in the pipeline. It can also be used for fluid adjustment and control. Compared with other valves, it has the following 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 break, and the sealing ability increases with the increase of the pressure of the medium.
5. Because PTFE and other materials 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 out. 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.
The electric ball valve is a rotary valve with a 90° angle of rotation. It has excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance. Equipped with electric cylinder type actuator. Products are widely used in system control in the chemical, petroleum, textile, power, food and pharmaceutical, refrigeration, and paper industries.
