Ball Valves

Die LÜDECKE ball valves are used as shut-off valves in pipe systems.
The way they work is simple:
In the fitting, a ball serves as shut-off device which opens and closes the fitting by a 90 degrees rotation. Due to full passage (which means the inner diameter of the bore in the ball is equal to the inner diameter of the connected pipeline) only small losses of flow occur.
They seal through special sealing rings which are mounted between ball and housing.
