High-pressure ball valve: High-pressure ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used to adjust and control the fluid. Among them, the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and hard-faced cemented carbide metal valve seat, which is especially suitable for media containing fibers and tiny solid particles. The multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels. Generally, this valve should be installed horizontally in the pipeline.
