Newlotoke Trunnion ball valves are a common type of valve that is commonly used in piping systems to control flow and pressure. Fixed ball valves are composed of parts such as balls, stems and valve bodies, the ball is usually spherical or hemispherical, and the stem is fixed on top of the sphere.

When the stem rotates, the ball rotates with it, controlling the flow in the pipe. There are many types of fixed ball valves, including one-way ball valves, three-way ball valves, four-way ball valves, etc., among which one-way ball valves only allow fluid to flow in one direction, while three-way ball valves and four-way ball valves can be used for diverting and mixing fluid flow.

The advantages of fixed ball valves are simple structure, easy to use and durable. In water treatment, ball valves are often used to control flow and pressure to support farmland irrigation, urban water supply and underground drainage. In general, fixed ball valves, as a common type of valve, play an important role in various fields.
