Abstract
The invention relates to a valve having a movably arranged valve body for selectively opening and closing a valve passage, with a sealing element, for example a lip seal, being arranged on the valve body in such a way that the sealing element comes to bear against a valve seat if the valve body is moved in a closing direction, and with at least one outer peripheral section of the sealing element being resiliently movable or elastically and/or flexibly deformable substantially in the movement direction of the valve body, and with a protective collar being arranged radially outside the outer peripheral section of the sealing element, which protective collar is fixed to the valve body in order to protect the sealing element from damage and/or from excessive deformation.
