A ball valve is a quarter-turn shut-off valve widely used in water distribution, HVAC, fire protection, natural gas, energy and industrial process systems.
A drilled metal ball inside the valve rotates 90° to fully open or completely shut off the flow. This simple operating principle provides reliable sealing, low pressure loss and long service life.
VANEX VALVE full-port flanged ball valves are engineered for maximum flow capacity, high sealing performance, durability and dependable operation in demanding industrial applications.
Working Principle
The valve contains a precision-machined ball with a through bore.
When the handle is turned, the stem rotates the ball.
Open Position
Handle is parallel to the pipeline.
Ball bore aligns with the pipeline.
Full flow with minimum pressure loss.
Closed Position
Handle rotates 90°.
Solid side of the ball blocks the flow.
PTFE seats provide bubble-tight sealing.
How to Open
Turn the handle.
The stem rotates the ball.
The ball turns 90°.
The bore aligns with the pipeline.
Flow begins.
How to Close
Rotate the handle another 90°.
The solid side blocks the pipeline.
Flow stops completely.
PTFE seats ensure reliable sealing.
