The invention relates to a valve having an inlet and an outlet, and a closure member. The closure member comprises an inlet area with a plurality of inlet openings and an outlet area. Main flow channels extend from initial openings in the inlet area through the closure member to openings in the outlet area, said initial openings are located in an initial flow inlet area of the inlet area which is first subjected to fluid from the inlet of the valve when the closure member is rotated from a fully closed position towards an initially open position.

The invention relates to an attachment ring for attaching an object in a flow channel. The attachment ring has a first surface for contacting the object and a second surface for contacting a surface of a shoulder. An expansion member expands the attachment ring by pushing the ends away from each other when the expansion member is moved into the opening. At least one of the second surface of the attachment ring and the surface of the shoulder is inclined in order to wedge the attachment ring between the surface of the shoulder and the object when the attachment ring is expanded by the expansion member.
