Electric ball valve

Electric ball valve introduction

Electric ball valve is composed of different structure ball valve and on-off or regulating electric actuator.Electric ball valve is an important actuated automatic valve in industrial automation control system.Electric ball valve is a valve that rotates around the axis of the stem according to this movement of the ball.The variation of the seat orifice is proportional to the ball stroke.Electric ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control.

Electric ball valve is a kind of pipeline pressure element for industrial automation process control. Electric ball valve is usually used for remote on/off control or regulating control of pipeline media.Electric ball valve is mainly used to cut off or connect the medium in the pipeline, and which can also be used for fluid regulation and control, in which hard sealing V-type segmented ball valve has a strong shear force between its V-type ball core and hard faced metal seat, especially suitable for containing fiber, small solid particles and other media.

Electric ball valve feature

1. The thrust bearing reduces the friction moment of the electric ball valve stem, making the stem stable and flexible for long-term operation.
2. Anti-static function of electric ball valve: spring is set between the ball, Electric ball valve stem and valve body to export the static electricity generated during the switching process.
3. Service life of the electric ball valve is long.
4. Lower type electric ball valve stem and stem head convex order to prevent the stem ejected, such as fire caused by stem seal damage, convex order and electric ball valve body can also form metal contact, ensure the stem seal.
5. Small fluid resistance, electric ball valve is the least resistance of all valves, even if the diameter of the ball valve, the fluid resistance is quite small.
6. Electric ball valve seat sealing performance is good, using PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and the ball valve sealing ability increases with the increase of media pressure.
7. Electric ball valve stem seal reliable, because the stem only as if rotating without lifting movement, ball valve stem packing seal is not easy to destroy, and sealing ability increases with the media pressure.
 

Electric ball valve working principle

Electric ball valve has a rotation action of 90 degrees. The body is a ball with a circular through hole or passage through its axis.The ball valve in the pipeline is mainly used to do electric ball valve cut off, distribution and change the flow direction of the medium, it only needs to use a rotation of 90 degrees of operation and a very small torque can close tight.Ball valves are most suitable for the use of switch, cut off valves, the development has been designed to make it have throttling and flow control, such as the V-type ball valve.Electric ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields.The ball valve body may be integral or modular.
