A device including a valve array which is adapted to allow and block a fluid flow, wherein the valve array includes: a fluid channel; a valve seating; and a closing body, for example a rotationally symmetrical or spherical closing body, which is arranged in the fluid channel. The valve array is configured to allow a fluid flow when the closing body is lifted off the valve seating, and to prevent a fluid flow when the closing body rests against the valve seating. The valve seating is formed by a valve seating body, for example an annular valve seating body, which is arranged in or on the fluid channel.
