The floating ball valve is a kind of valve in which the ball is not rigidly held on its rotational axis and so is free to float between seats. Sealing is achieved by the action of the pressure, which pushes the ball against a seat and the body construction is two pieces, bolted joint, made by forging, forged or rolled bar.

The floating ball valve is one of the possible types of on-off ball valves, that are shutoff valves suitable for use in various types of processes, available in different pressure classes.
