Obit Ball Valve is a lifting rod-type ball valve;

When closing the valve, turn the hand wheel to lower the valve rod. The spiral guide rail on the valve rod interacts with the guide pin to make the valve rod and the ball rotate at the same time, so that the ball rotates 90 degrees without friction. Continue to turn the hand wheel, and the valve rod descends again to make the ball contact with the valve seat

When the valve is opened, due to the interaction between the guide pin and the guide rail groove, the valve rod acts on the ball to make the ball rotate 90 degrees after it is separated from the valve seat. There is no friction between the valve seat and the ball when the valve is opened
