Abstract: As the name suggests, the electric ball valve is mainly a valve that is driven by the valve stem and rotates around the axis of the valve stem, and is equipped with an electric actuator.
It is mainly used to cut off or turn on the medium in the pipeline, and can also be used for fluid regulation and control. The hard seal V-shaped ball valve has a strong shear between the V-shaped ball core and the metal valve seat of the hardfacing alloy. Shear force, especially suitable for media containing fibers, tiny solid particles. The electric ball valve is divided into an electric flange ball valve, an electric pair ball valve, an electric welding ball valve, and a electric wire ball valve. According to the sealing form, it is also divided into a soft-sealed electric ball valve and a hard-sealed electric ball valve.
Here are the six advantages of electric ball valves:
(1) Simple structure, small size and light weight.
(2) The fluid resistance is small, and the full-diameter ball valve has substantially no flow resistance.
(3) The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally active, and it is convenient to disassemble and replace.
(4) Since the ball valve has wiping property during opening and closing, it can be used in a medium with suspended solid particles.
(5) When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the sealing surface of the valve.
(6) Close and reliable. It has two sealing faces, and currently the sealing surface material of the ball valve is widely used in various plastics and sealed.
Do you know the electric ball valve? The following vertical valve introduces the working characteristics of the electric ball valve. If you don't know, let's take a look!
First, it is suitable for the process and fluid control system of the switch with large pressure difference, strict sealing requirements and cutting the pipeline medium.
Second, the working temperature: -20 ° C to +150 ° C (+250 ° C special seal).
Working pressure: PN16, PN25 - PN40 - PN64 -PN100
