Abstract:
A soft-sealing, concentric butterfly valve for mounting with grooved couplings or flanges in a pipe system. The butterfly valve comprising a valve housing with a through running boring with a rotary damper, mounted to a spindle placed upright in a circular-cylindrical valve seat, said valve seat being equipped internally with conical contact surfaces for the damper, and the valve housing comprises on a first side a coupling end piece cast in one piece with the valve housing and equipped with an external circular groove. The valve has a removable coupling part, comprising a second coupling end piece equipped with an external circular groove, mounted to said second side of the valve housing, and said valve seat is compressed between the valve housing and the removable coupling part and surrounds the damper to provide a leak proof connection.

Claim (Index 13):
A method for alignment of a first pipe and a second pipe in a pipe system, comprising:\n placing a butterfly valve between said first pipe and said second pipe, wherein the butterfly valve comprises: a valve housing with a through running boring, a rotary damper, mounted to a spindle, placed upright in a circular-cylindrical valve seat in the valve housing, the valve housing comprises on a first side of the through running boring a first coupling end piece cast in one piece together with the valve housing and which is equipped with an external circular groove, the valve housing comprises on a second side of the through running boring a removable coupling part with a second coupling end piece which is equipped with an external circular groove, said removable coupling part has a through running boring aligned with the through running boring of the valve housing, and said valve seat is equipped internally with respective conical contact surfaces for the rotary damper, wherein said seat is compressed between the valve housing and the removable coupling part and surrounds the damper to provide a soft-sealing concentric butterfly valve with a leak proof connection, wherein the method further comprises the steps: connecting the external circular groove of the first coupling end piece with a first coupling groove of the first pipe using a first clamp, and connecting the external circular groove of the second coupling end piece with a second coupling groove of the second pipe using a second clamp.
