Product Description

The ball of the floating ball valve is floating. When the valve is closed, the pressure of the fluid causes the ball to move toward the valve seat, thereby closely contacting the valve seat and forming a seal. When the valve is opened, the rotation of the valve stem drives the ball to rotate, allowing the fluid to flow through the hole in the center of the ball.
