The first butterfly valve in the world which is not using a regular cone for it´s seat design. In the newly designed V-AXX® valve, the seat shape can be changed around the whole seat without restrictions. If necessary, the angle of the seat, even in the shaft area, can be 25° or more, without changing the angle in other areas. This is only possible due to the unique seat design, which is not formed by a simple cone but by a much more complex figure, not yet named in geometry. LATEST TECHNOLOGY IN BUTTERFLY VALVES DESIGN In previous designs, the seat shape never changed along its 3D figure, but in the newly invented design, the lines forming the outside shape do not cross in the same point as in a cone. Basically, this means the designer is free to design the seat angle all the way around the seat. If necessary, the shaft offset from the pipe centerline could be brought to zero and still produce a friction-free valve.
