Abstract
A valve disc for a butterfly valve. The valve disc includes a disc body, a main groove suitable for receiving a seal element, and an introduction groove. The disc body comprises first and second faces, an outer periphery, and at least one engagement means configured to receive a shaft for coupling the valve disc to a valve body of the butterfly valve. The main groove extends along the outer periphery to form a continuous groove. The introduction groove has a centreline (CL) and extends from a groove mouth opening in one of the faces of the disc body to an intersection with the main groove. The main groove is so dimensioned and configured that a seal element can only be inserted into or removed from the main groove via the introduction groove. Optionally, the valve disc is a single continuous body of material.
