Abstract

The disclosure relates to a valve assembly, comprising a valve body, in which a fluid channel is formed that connects a fluid inlet to a fluid outlet, wherein a preload force is applied to a closing body, which is movably mounted in the fluid channel, in the direction of a valve seat formed in the valve body, a fluid force acting on the closing body against the preload force in order to open the valve seat. The closing body is guided axially and/or radially by at least one guide ball, the guide ball being arranged between the closing body and a lateral boundary of the fluid channel.
