Abstract
A shut-off element of a hydrant with a hydrant axis. The shut-off element has a valve stem that is axially movable substantially along the hydrant axis, and a main valve body that can be brought into sealing contact with a sealing surface of the hydrant. The shut-off element has a damping system that is inserted between the main valve body and the valve stem or in a section of the valve stem or between an actuating element of the valve stem and the valve stem or in the actuating element itself, so that the main valve body is coupled to the valve stem axially dampened by the damping system along the hydrant axis.
