Short Description
A ball valve is a type of valve that uses a spherical disc (the “ball”) to control the flow of fluids (liquids or gases).
The ball has a hole (bore) through its center; when the bore is aligned with the pipeline, flow passes freely, and when rotated 90°, the flow is completely shut off. Ball valves are widely used because they provide tight sealing, reliable performance, and quick operation with just a quarter turn.
Key Features

- Long service life with minimal maintenance
- Low torque operation and easy to automate
- Available in floating ball or trunnion-mounted design
- Full-bore design available for minimum pressure drop
- Applicable for both on/off and throttling functions
