​The floating ball valve is a quarter turn valve which uses a rotating ball with a hole through it, which can be aligned with the flow path (open position) allowing flow and blocks flow when the ball is rotated by 90 degrees. A floating ball is where the ball can float against the seals. In normal operation, the ball will float downstream slightly, causing the seating mechanism to compress under the ball pressing against it, thus using the system pressure to increase valve sealing. Ball valves are used for on/off and throttling services.

​Brooksbank Valves are one of the UK's leading floating ball valve manufacturers. For over 65 years we have been supplying ball valves to the Gas and Chemical industry the world over.
