• a first valve seat configured to be closed by the first valve body and arranged on the housing at a lower portion of the valve along the longitudinal axis;
• a first connection arranged circumferentially to the first valve body relative to the longitudinal axis;
• a second connection arranged end face-on to the first valve body and aligned with the longitudinal axis;
• a first fluid flow path extending from the first connection via the first valve seat to the second connection;
• a movable second valve body formed separately from the first valve body;
• a second valve seat closeable by the moveable second valve body;
