Ball Valves

About Ball Valves

Ball Valve is a quarter-turn operated valve. Ball Valves consist of a closure membrane which is a spherical plug with a through hole. A ball valve is a type of valve that uses a hollow, perforated ball to control the flow of fluid. The ball is rotated 90 degrees to open or close the valve. Ball valves are typically used in applications where a quick shutoff is required, such as in the water and gas industries. They are also used in applications where the flow of fluid needs to be controlled, such as in chemical processing plants.When the valve is open the through hole is in line with the fluid flow and it allows the fluid to flow through it. The valve can be closed by rotating the globe by 90 degree. such that the hole now becomes perpendicular to the flow and thus stops the flow.Its sheets are usually made up of soft materials to offer tight shutoff. Sometimes sheets can be made from plastic and metals. These valves are not recommended to be used in partial open conditions.A large pressure drop occurs in open conditions of the valves due to misalignment between the direction of flow and the opening of the plug.
