Valve is the most common in our lives, and it is also the most indispensable control in industry. There are more and more types of valves now, and the best one currently used is the ball valve. Ball valves are very important in our industry. The ball valve is actually a valve whose opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It has very good functions of converging, dividing and switching flow directions. The three commonly used ball valves are pneumatic ball valves, electric ball valves and manual ball valves. So next, the editor will tell you about the knowledge about ball valves.

Ball valve price

Ball valve (ball?valve?) is defined in the standard GB/T21465-2008 "Valve Terminology" as: the opening and closing parts (ball) are driven by the valve stem, and A valve that rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal valve seat with hard alloy surfacing. It is especially suitable for materials containing fibers and tiny solid particles. etc. media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction switching of media on the pipeline, but can also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode.
