Operating Principle
Inside the valve body is a bore-drilled spherical ball that rotates freely. When the handle is turned 90°, the ball's bore aligns with the pipe, allowing unobstructed fluid flow. Turning the handle back brings the solid side of the ball against the seats, completely blocking the flow.
The combination of precision-machined POM seats and NBR seals ensures a tight shut-off, even under high pressure and system vibration.
