Electric ball valve is a new type of ball valve, which can also be called electric actuated ball valve. It has some unique advantages of its own structure. For example, the switch has no friction, the seal is not easy to wear and tear, and the opening and closing moment is small. This reduces the size of the actuator. With multi-rotating electric actuator, the medium can be regulated and severely interrupted. This electrically operated ball valve is widely used in petroleum, chemical industry, urban water supply and drainage and other strict cut-off conditions.
Electric ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline.
Ball valve is a new type of valve widely used in recent years. It has the following advantages:
- 1. Fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.
- 2. It has simple structure, small volume and light weight.
- 3. It is tight and reliable. At present, the sealing surface material of ball valves is widely used in plastics and it has good sealing performance. It has also been widely used in vacuum systems.
- 4. It is easy to operate and fast to open and close. It can be easily controlled over a long distance by rotating 90 degrees from full to full shutdown.
- 5. Its maintenance is convenient. The electric ball valve has simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.
- 6. When fully open or fully closed, the sealing surface of the sphere and seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the sealing surface of the valve.
- 7. It can be used in a wide range of applications, ranging from small to several millimeters in diameter and from high vacuum to high pressure. When the sphere rotates 90 degrees, it should present all spherical surfaces at the inlet and outlet so as to cut off the flow.
