Function
Ballvalves have a ball with a bore hole inside the valve housing. When the valve is open the medium flows through this
bore. When the valve is closed by turning the lever by 90° the
ball is turned accordingly. The valve opening is closed as the
bore then lies crosswise to the valve opening. The pipeline is
shutoff.
