A ball valve is a type of quarter-turn valve that controls flow using a hollow, perforated, and pivoting ball inside the valve body. When the ball’s hole is aligned with the pipeline, fluid flows freely; when rotated 90 degrees, the flow is completely blocked. This simple mechanism makes ball valves highly reliable for shutoff and control applications. Ball valves are known for their tight sealing performance, durability, and ease of operation. They can handle high pressure and temperature conditions, and are suitable for gas, liquid, or even corrosive media, depending on the materials used. With minimal pressure drop and fast on-off control, ball valves are widely used in industries like oil and gas, water treatment, chemical processing, and general plumbing. They come in various types such as two-way, three-way, floating, and trunnion-mounted, and can be operated manually, pneumatically, or electrically.
