IMPROVED BUTTERFLY VALVE ABSTRACT OF THE DISCLOSURE A butterfly valve comprising a body 1, a passage 2 extending through the body, a closure or butterfly member 3 mounted in the passage 2 to pivot about an axis orthogonal to the axis of the passage so as to be movable between a closing position in which a sealing element fixed or formed on the periphery of the disc of he closure member has a sealing contact with a seat 8 carried by the body and a fully open position roughly perpendicular to the closing position, the peripheral surface of the closure member 3 and the conjucate surface of the seat 8 being conical surfaces defined by two cones of revolution, while the axis of rotation of the closing member is offset along the axis of the passage in a direction away from the apex of the cone defining the sur- face of the seat relative to the mean plane of the disc of the closing member, wherein for a given value of the apex angle 24 of the cone C1, defining the seat of the valve and for a given position C of the axis of rotation of the butterfly member in an orthonormal system Ox,yx,z of which one of the axes is coincident with the axis of said cone,there is defined a joint plane of the butterfly member with its seat of which a couple of points in respect of which the minimum angle of disengage- ment is maximum, has for trace a point Q located in the plane (Ox,Z) of the system and of which the coordinate and the angle of disengagement are given by the following approximate: Image
