Ball plugs

A ball valve is a pipeline valve consisting of a body, a shut-off element in the form of a ball connected to a handle and designed to shut off the flow of the working medium in the pipeline. The plug is installed and rotated in the supports, it has an axial projection (trunnion) in the lower part, entering a special recess, and the seats are pressed against its spherical surface under pressure. This design significantly reduces the efforts required to operate the valve and allows the use of drive devices of lower power than for valves with a floating ball.
