ABSTRACT:
A butterfly valve with a seal face (4)having two opposite, essentially spherical sections (h, i) intersected by a symmetry plane (k) through the throttle which coincides with an axis through a point (n) parallel with the torsional axis (j) of the throttle and two opposite, essentially conical sections (f, g) on both sides of the symmetry plane. The spherical and the conical sections successively merge into each other. When the throttle is revolved to shutting position, the sealing line (a) which has circular shape is pressed against a valve seat (18) shaped as a circular ring made of steel. An eccentrical location of the torsional axis (j) will cause that a surface contact between throttle and valve seat wil occur simultaneously along the entire sealing line in the shutting movement.
